Physics C is the only one of those where I used a prep book because I self studied. I would suggest barron's, I did a comparison of Barron's vs.
PR on another thread (Best Ap review books, started by xxsteelxx) Also for SAT II physics, you might want to get another prep book, because that covers stuff not covered on physics C (waves, thermodynamics and modern physics) although with taking physics C, you will be very very well prepared for Mechanics and E&M.
I don't know about Spanish, sorry.
