If you're just looking for a supplement, I recommend Calculus for Dummies and its companion Calculus Workbook for Dummies. Your local bookstore might have them; they're pretty common.

I used the first edition of the Dummies book ten-ish years ago to refresh my knowledge of Calc 1. I went through the whole book and thought it did a good job of explaining stuff. The workbook is good because it has complete solutions, which are important for learners.

I'm not a fan of the Larson series of textbooks. I find them to be outline-books that don't do a good job of explaining ideas.
