You're in luck! I just discovered some Linear Algebra tutorials on Wolfire's blog that I felt were really good. The guy writing the tutorials, David, has such a killer way to explain the stuff. It's extremely handy for those that are weak at math since it is showing more practical application than theory (which is what someone weak could use)
Part 1 - Vectors addition, subtraction, scalar-vector multiplication
I was just about to pick up "Tricks of the 3D Game Programming Gurus" (volume II). It seems really good on the 3d theory side and keeps everything simple from what I saw. I tried to pick up Direct3D/OpenGL alone but I'm like you - I had no idea.
