Spivak is good and well-loved and even has a sense of humor.

Note that there are two ways to learn calculus: the high-school way, without proofs (Stewart is a good example) and the college-level way, with epsilon-delta proofs (Spivak is this kind.) You should decide what fits your needs best. You don't necessarily need to learn high-school-style calculus first -- my first intro to calculus was Serge Lang's book, which is similar to Spivak but more compressed -- but if you're just getting started computing derivatives it may help to do some physics problems to build intuition.
