My ocz agility 3 60 gb works fine; some of the other models have not. Patriot is also ok, and honors their warranty (I sent in two defective units, but that model has been discontinued; they sent me a newer model that works fine). I use gskill and patriot ram; both work fine. Get a 1.5v version either 1333 or 1600. Can't answer your question about ssd cache; I usually clone mine as my files are small. After installing windows, you can connect your old drive and windows will configure it as a secondary drive. Use only one drive when doing a fresh install of windows, then add the other drives while windows is running. You can't have more than one primary drive connected at a time.
