Which is the BEST test prep book for the SAT, ACT,or any of these AP tests?

AP Economics, AP Psychology, AP Government, AP Physics B, and AP Literature.

Will I be ready for the SAT Subject test?

If I take English Lit. AP, Physics AP & French AP, will the preparation for the AP exams be good enough for the SAT subject tests in those areas? Would I need to learn new stuff for the SAT subject tests and would I need a tutor?
