My biggest questions concern taxes. I am/will be in the highest tax bracket since I'm still working for another few years with the company that acquired us. Is BND OK or should I have more in VWIUX or another muni fund?
If you are in the top tax bracket (39.6% plus 3.8% ACA surcharge), or even the 33% tax bracket, you don't want BND; you should be using muni funds for all of your nominal bond holdings. Intermediate-Term Tax-Exempt is a well-diversified, high-quality fund, so it's fine for your entire holding. (If there is a muni fund for your state, you could save even more in taxes, but you probably wouldn't want to put more than half your bonds in one state.) If you change to a lower tax bracket when you retire, you can switch back to taxable bonds for little if any tax cost.
You should buy I-Bonds in preference to TIPS, because they are tax-deferred, but the $10,000 limit means that they won't make much of a difference. TIPS income is taxed at your full tax rate, but with the current low yields, there won't be much income to tax, and it is exempt from your state tax.
VWO/VEU (Emerging Markets; FTSE All-World Ex-US) is not a natural pairing of funds, as VEU holds emerging markets as well. It's probably better to either use Total International (VTIAX, or the ETF VXUS), or else 65% VEA/20% VWO/15% VSS to get a similar allocation that is more complicated but slightly more tax-efficient.
In your tax bracket, REITs are going to create a huge tax bill, probably 1.5% per year. If you want to hold them, you are one of the few investors who would be better off in a variable annuity; it's better to pay the 0.58% expense ratio on the Vanguard Variable Annuity REIT index, tax-defer your gains, and then pay regular tax on your gains when you withdraw. And as much as I like VNQI (Global Real Estate), I think you should limit your holdsing to what you can fit in an IRA.
