The credit card/rewards thing was just an idea I had. I have no credit card debt at all, my schooling has been paid off, and my wife and I are currently renting. My intent was to pay off all my debt and possibly gain the rewards points in the process.
I am in a position where I could pay off my car loan which carries a 6.25% interest rate and still have a substantial savings. However, it makes sense to not deplete my savings too much. Maybe the best thing to do is to pay off my car loan in the next 12 months with 4 large quarterly payments.
