Rear Disc Conversion
Well i just ordered my rear disc conversion that came with the E-brake cable. I am wanting to know which master cylinder and brake booster i should get...Should i just get the ones for a 93-95 SI hatchback?
That'll work just fine. You shouldn't need the booster though, just the MC. You can actually leave your stock one on there if you want, but most people prefer the firmer pedal feel of the larger MC. Also be sure to find a rear-disc proportioning valve (stamped 4040) to make sure those rears are getting enough juice.

h: the drum brake system runs a high pressure rear to accomodate for the distance teh wheel cylinder has to push the shoes against the drum. Most people find that without changing to a 4040 prop that the rear calipers tend to bind or stick because they are rated for a lower amount of force over the area of the piston

I wouldn't bother myself, but that's just how I am.
If you're unhappy in any way w/ the current MC, or think it might be showing signs of age and have future problems, than now would be the time to change it. They're very similar cars, even by 5th gen civic standards, so I don't see why the MC would differ, but at the same time I don't see why the Si would come with drums in back either so... I know why they did it, but I guess I don't approve.
edit: :goodjob: on the change btw, the convenience alone when changing pads/shoes is well worth the trouble IMO, especially if you get a good deal on the new calipers, rotors, etc.
