I agree jIM that international is probably an important sector(s) that has been overlooked here. The OP is diversified across the US markets, but diversification could be extended even further. The inevitable overlap of 33 funds should also be corrected.
All this tax talk and nobody is touting ETFs? Of course, sales in a taxable account will still be subject to cap gains/losses. ETFs track a sector and/or an index so 6-8 funds could thoroughly diversify the OP. AVERAGE expenses are .09% as compared to 1.4% for mutual funds. There are brokerage transaction fees but they can be minimized in todays competitve online trading world. They trade midday (no missing out on an intraday price climb). They are usually more tax efficient than MFs as they don't spin-off capital gains. And although it probably doesn't apply here, they can be margined and/or optioned.
