After arithmetic, the typical order of classes (The ones I took, and the one I believe most often taught in American schools) goes like this:

Algebra Geometry More Advanced Algebra Trigonometry Calculus

I don't have any book recommendations and I don't know of any books that would cover all those topics. There are many books on algebra however, and I don't think it will particularly matter which one you use. It should get you up to speed very quickly.

The other topics are probably less important for intro CS. I don't think I ever used calculus or trig for any CS classes. Very basic geometry might be used as examples.

That order is really very helpful, thank you. That order plus the Khan academy is what I am going to base my study on for now.
