The main reason my list is so complex is that I already own some of these investments (4 stocks, VTI, VWM, Gold, Lending club, etc...) The ones I am adding are the recommended "simple" ones VTSAX, etc... I am also selling out of probably 40!!!! different mutual funds that I am currently in and most likely facing a lot of capital gains tax. Talk about "simplifying"! I may do some this year and some after the 1st to soften the blow.
You are moving in the right direction, Macrocide--keep going. Consolidating your investments in one house (Vanguard in your case) will help because you can exchange funds (rather than selling and buying), thereby avoiding capital gains taxes. This is also a plus for funds over ETF's.
Throw those 40 funds into a spreadsheet and calculate the capital gain or loss for each. If you are lucky (unlucky?) you can offset some of the gains with some of the losses and schedule your sales accordingly.
About those bonds... Bonds are not about making money--that's what equities are for. You hold bonds as a shock absorber for when the stock market drops. If you hold no bonds you either have a very high tolerance for risk (a 50% drop in the market wouldn't upset your plan) or you believe that the market will continue to rise indefinitely.
There's been a lot of press about what a terrible year it's been for bonds, so let's do the math.
http://quotes.morningstar.com/fund/f?t=VBTLX®ion=USA shows that the mid-year drop in bonds was about 4%--the worst drop since the nineties. Since then bonds have rebounded so they are now off about 2% for the year. The point is that a terrible drop in the bond market is about 4%. If your asset allocation was 25% bonds that would be a 1% hit to your portfolio (or .5% year-to-date). So that's the downside risk to owning bonds--not too bad, really.
Now let's consider a big hit to stocks--50% just a few years ago. If you held no bonds, your hypothetical portfolio would be down $500,000. If you held 25% bonds, your equities would be down only $375,000 AND your bonds would have continued to plod upward about 3% per year ($22,500). So the 25% bond allocation would have left your portfolio with $647,500 instead of $500,000--a pretty good shock absorber, considering the small downside risk.
