I would personally consider the following:
1.) pay off the $5k personal debt. Makes no sense to have that.
2.) follow your current investment strategy and asset allocation. Unless you don't have one.
3.) If you don't have one, you could get a lot of bang for your buck by using that 10% to diversify your heavy equity holdings and smooth some volitility. You wouldn't sacrifice long-term gains, especially with occasional rebalancing. The best options in my opinion would be a) TLT (long-term US treasuries), or b.) GTU (gold). GTU could be bought now (it's nearly 20% off its highs); TLT is near all-time highs, so I'd either dollar-cost average in or give it 3-6 months to drop back down around $100. See the effects here:

4.) Have you considered trying to develop an additional income-stream? Like a rental property? In my area, starter-single family homes are extremely affordable, and can produce very nice positive monthly cash-flow. That's where I'm looking right now. I would only buy something that is positive cash flow. Nothing else (stocks, bonds, gold, farmland) looks cheap now. Gold in the $1200-1500s is probably worth a look, and if silver gets down to $20-25 range, I'd consider speculating there too.
5.) Keep it in cash, until something jumps out at you as a huge bargain. There is a big advantage to keeping some cash for when things go on sales (stocks, etc...).
