I agree with the above two...it's probably most important that you get a decent algebra foundation. It's my understanding that pre-calc covers the necessary trig concepts anyway, right?
When I started calc with a less-than-ideal background, it was algebra that I had to spend a week or two retraining myself in. There was some trig I had to relearn along the way, but I would have been lost had I not beefed up my algebra.
