Sam,
I know (from your other posts) that you like risk and after your experiences leaving Vietnam everything might seem low risk after that.
But have a look at some of the junk bond prices -- what is happening to GMAC bonds these days. They are high yield for a reason.
You seem to have a yearning for things that pay a lot of interest. Why? You pay tax on it now and you don't need the income because you are still working.
Better to have things which will crank out capital gains that you don't have to pay taxes on until you realize those gains -- maybe never, or many years from now, and dividends and capgains are taxed less than interest and income. A lot less.
You have no large US stocks, it appears. We may all love to hate the S&P megacaps but they aren't that toxic. In fact they may be ready for a run now.
You could treat your current savings from your job as if they were a bond coupon, and add that in as if you held bonds in your portfolio in the equivalent amount, and then maybe go for a 50% stock 50% "bond" blend.
In other words, if you save 20k per year and your job is secure and you like it, consider that is like earning 20k of interest on a bond that earns, say 5%. That would imply a bond position worth 400k. If your other savings are 600k, then you could argue, for asset allocations' sake, that you have a 1million portfolio, Then allocate out 50-50 or 40-40-20 (with the 20% being 'other' - Reits, Commodities, Oil/Gas, private company investments etc) In that case, you might then go to 400k of Stocks, 200k of Reits/other and the bond position is covered by your job that is reliably paying your 20k a year in savings. That would mean zero other bonds -- and in your case give you an excuse to dump the junk.
It may not suit everyone but it is worth considering.
For your stocks side, though, my advice would be 50% in US, 50% in foreign, split roughly into 2/3 large cap, 1/3 small cap in each. Low fees, reliable fund companies.
