the only tricky part is getting the lines loose without stripping them out. Get a set of line wrenches to get them off without messing them up.
If you don't break the bleeder screws at the wheels loose, you shouldn't have to bleed the lines out again. No air will enter the lines normally if you are careful.
There is also a connection under the dash that hooks the master cylinder to the brake pedal. Normally its a cotter pin (easy to remove) but pay attention to the brake light switch and how it mounts on there. Remove it, the lines under the hood, and the 2 bolts holding the MC on, then reverse the procedure to install the new one.
Should take you about 30 minutes at the very most (an experienced mechanic will do it in less than 10 minutes).
Have fun with it, its pretty easy!
