Here's a good site on some calc/pre-calc stuff:

I actually use that to study for my calc 2 class (well, up until they stopped covering more advanced topics). It'll teach you the basics of calc, like derivatives and all that good stuff.
If you're good at algebra, you'd just need to brush up on stuff like logarithms. You don't need trig so much... at least, I haven't needed it yet in calc 2 aside from the basic "cos = adjacent / hypotenuse" type of stuff when doing trigonometric integration. Then again, you'd just need to know that tan = sin/cos, or csc = 1/sin, sec = 1/cos, cot = cos/sin, etc.. and the basic identity functions (like cos^2 + sin^2 = 1), but that's really all in pre-calc.
[edit]
Now that I think about it, I never ONCE had trig. Ever. I never struggled in pre-calc either because of it, so I'd say don't worry about it that much.
