Re: release bearing
If you gotta pull the tranny my thought would be just to go ahead with it all. If its hard to get into gear its probably that release bearing and possibly worn clutch. But yes clutch kit (includes pressure plate, clutch plate pilot bearing and release bearing), slave cylinder and flywheel.
