91' CRX hf replace clutch

Heard a few mentions of pulling the motor out to rebuild clutch (which is slipping). Sure would like the low down on this situation before I commit to spending the bucks. I attempt a few repairs on my own but know when not to. Appreciate advice that tells me straight to replace the water pump if the motors out anyway........anything else?? Thank the gods for guys who love cars. I like my car stock and running tip top.
