Which ones and how many you use is pretty much personal preference. Do you want to use 2 funds (500 and Small cap) or 3 funds (500 and mid and small cap) to get something close to total stock market? Ignore this - when I got to the contributions, I found that all of your 401k needs to go to bonds.
For the bonds, the VG long term is the best cost, but I'm not fond of long term bonds, so I'd temper that by mixing it half and half with the PIMCO Low Duration bond.
I moved things around to the order I'm accustomed to (so I can find things easily) and this is what you currently have (other than I exchanged the Nuveen Real Estate into the Vanguard long term bonds in the 401k).Taxable

$50,000 taxable (for retirement, not short term goals) <---$14k to Total International, $36k to Total Stock Market although some of this might have to go into a muni bond fund to keep your bond ratio up to target
Next year (2014) you will almost certainly have to put some of the $50k going into the taxable account into a muni (tax-exempt) bond fund.
Does that help?
