No offense, but it appears from your questions you have not previously done this job. A couple words of caution:
1) The transmission is heavy. Having a transmission jack is highly recommended. If not, a strong friend. Don't try and muscle it out by yourself. Good way to get hurt. Don't ask me how I know this.
2) Be careful not to let the transmission 'hang' in place once you've started to slide it out. Letting it hang will likely bend the clutch disc center. Perhaps you're replacing the disc and don't care, but it's still not recommended. Best to support it well and slide it all the way back/out in one motion, until the input shaft is clear of the bell housing opening, then lower it.
3) You'll need to provide support at the rear of the engine. A scissors jack with a board across the back of the oil pan would suffice.
4) Transmission fluid will run out of the rear end of the 4 speed. If by chance you have another slip yoke, put it in the rear of the trans before starting to pull it out. If not, a couple good baggies slipped over the end and secured with strong rubber bands or duct tape would work.
5) Remember to disconnect the battery!
6) Removing the shifter and linkage arms allows the trans to come out a bit cleaner in my experience.
Good luck!
