Not at all. It is perfectly possible to do bit-banging in C. It may be
tricky if you need cycle-exact timings, but then you can always use
inline assembly or create small assembly-only routines called from your
C code.

Don't worry. If you have some spare FLASH, even the 16F devices are
perfectly usable in C.

I suggest Hi-Tech PICC. The code it generates is so efficient that I
would hardly feel compelled to try to improve it in assembly.
