If you really want to do vector multiplications, you'll run out of registers. Hence, use MULs with constants for the camera vectors (like MULS.w #cam,Dn) and replace the dummy value with your updated camera values for each frame (self-modifying code). In this way you can do point projection without having to juggle with registers.
