I've been lurking for a few weeks. This is my first post!

I listed my questions first (there are a lot), but I have completed the required form below.
Thanks in advance.
P.S. I'm sending this to my CPA/CFA. I just want to run it by you guys as well. This form has been very useful to fill out. It actually forced me to learn about our plans.

QUESTIONS
----
0. Does the plan (listed at the end) make sense/seem reasonable?
1. Where is the best place to put my money from the sale of my stock? Once I sell, the money will sitting in a well known discount broker. Should I move it to a Vanguard taxed brokerage account? Can I move a portion of it to an IRA (given our income)?
2. If we pay down a portion of the principal on our mortgage, will it reduce our monthly payment, or just reduce the total number of monthly payments?
3. My wife and I are planning to have kids. Should I start saving for college now? If so, what is the best way to invest for a child that hasn't yet been born? Is taxed brokerage account the best way to go? It seems most other ways require the child to be born.
4. I don't believe that I can invest in a Roth IRA (given our income). Is this correct?
5. Is my math correct on the mortgage principal pay down in the plan below? All I need to do is pay the principal, and request for the bank to remove my mortgage insurance, correct? I believe this is law. Has anyone successfully done this?
6. Should I really just let my emergency fund sit in cash? Does it make more sense to keep 20k in cash, and 40k in money market?
7. Does it make sense to invest in REIT? I think real estate has taken a huge hit, so it makes sense to me to buy low. I also like diversifying a bit from stocks/bonds. In addition, I will keep it in a tax deferred account.
8. Instead of REIT, should I shift the 5% to bonds, and buy FID GNMA?
8. Am I allowed to roll my company plan into my Vanguard IRA even though I'm still contributing to my company 401k? Are there any caveats to this?
9. I am treating my wife's 403b plan like a 401k plan right now. Is there anything I should be aware of when doing this? They had a ton of annuity saleswomen lurking around the classrooms, but I advised my wife to sign up with Fidelity instead. Her Fidelity account appears to allow her to invest in mutual funds.
10. Should I consider a TIPs fund for a portion of my bonds?

Tax Rate: 28% Federal 9.2% State State of Residence
Age: 25 to 30
Desired Asset allocation: 75% stock/20% bonds/5% REIT

Pre-tax earnings: 175k to 225k
Total of all accounts: $476,125 (excluding emergency funds in Wells Fargo Savings)
== Wells Fargo Savings Account: 26,000 (emergency fund)
== Taxable Brokerage: 435,000 (91% of all non-emergency accounts)
91% XXXX
All of the money in this account is in a single (company) stock. Some of the shares are vested, and their value is 435,000 currently (I have more that have not yet vested). I can't yet sell any shares, but will be able to sell the vested shares "shortly". I am trying to avoid too much detail, as I don't want to expose who I am, but if you have more questions about this, please feel free to ask. All sales from this account will be taxed as regular income (I haven't exercised, or held any shares for > 1 year).
== Vanguard Rollover IRA: 14,228 (2.9% of all non-emergency accounts)

2.90% Vanguard Target Retirement 2040 (VFORX) (0.19%)
== Company 401k: 25,377 (5.3% of all non-emergency accounts)
I filled out a "profile" thing for this account a while ago, and it allocated my resources as follows:

0.31% FID FREEDOM 2050 (FFFHX) (0.80%)
No company match
== Public School Pension
My wife is a teacher in California, and will be elligible for CalSTRS, assuming it doesn't change (hah). Based on the little calculator on the website (and hypotheticals), if she retires between 53 and 55, she will make between 2200 and 3600 per month. Obviously, the longer she stays (up to 60), the more she gets. Staying to 60 gets her 5500 per month.
These are really rough estimates.
For more details see the CalSTRS website.

PLAN
----
1. Pay down mortgage to eliminate mortgage insurance. I believe that this will cost $51,980 (605,000 - (709,000 * .78)).
2. Add $34,000 to my emergency fund to increase it to a total of $60,000 (10 months).
3. Invest remaining cash in a Vanguard taxable brokerage account.
If we assume that, after taxes, my currently vested shares net me $217,000, then I would be left with $131,000 after the principal pay-down and emergency fund increase. Adding that to my existing Vanguard IRA, 401k, and 403b, I would have a total 131 + 14 + 25 + 2 = $172,000 of investible cash (41k of which is in tax deferred accounts).
== Stock (75% of investible cash)
xx% $dollars [account] fund SYMBL (expense ratio)
20% $34,400 [Vanguard Taxable Account] Vanguard Small Cap Index Adm VSMAX (0.12%)
35% $60,200 [Vanguard Taxable Account] Vanguard Total Stock Mkt Idx Adm VTSAX (0.06%)

14.5% $25,000 [Company 401k] PIMCO Total Return PTTAX (0.91%)
2.32% $4,000 [Company 403b] Spartan Intermediate Treasury Bond Index Fund - Investor Class FIBIX (0.20%)
== REIT (5% of investible cash)
xx% $dollars [account] fund SYMBL (expense ratio)
5% $8,600 [Vanguard IRA Account] Vanguard REIT Index Adm VGSIX (0.26%)
Total: 100% $172,000
Obviously, as soon as I strike this allocation, the accounts will begin changing. The major contributors to imbalance will be :
1. Sales of remaining unested company stock (vests monthly).
2. 401k/403b contributions, which will amount to 2750/month (excluding employer contribution) (16500*2/12)
Since my 401k and 403b contributions will always go into tax deferred accounts, I will continue purchasing the bond/REIT funds listed above, in matching proportions.
My company stock will go into my Vanguard taxable account, where I will continue purchasing the stock funds listed above. In the event that the Vanguard taxable account increases in value too quickly (do to company stock sale contributions), I will purchase Vanguard California Intermediate-Term Tax-Exempt Fund Investor Shares (VCAIX) (0.20%) in my vanguard taxable account to maintain a 75/25/5 mix.
