A couple of tips for brake jobs that you don't always see in the DIY's:
Really important - use only the best flare wrenches, like Snap-On or Mac. The rest are crap and will spread and round off your nipples if they are overly tight (oo, that sounds painful).
Brake fluid is one of the best paint removers you will find, Be careful not to spill it on any painted surfaces and if you do then wipe it up right away.
Have lots of clean rags handy and don't spare the brake cleaner. Compressed air is also very helpful. I believe that at least part of the reason that my brakes don't squeal is that the calipers were cleaned to operating room standards before painting and re-assembly.
A Motive power bleeder is worth every penny. Actually, it's worth twice that.
The clutch line comes out of the side of the reservoir, not the bottom like the brakes. Do not let the fluid level in the reservoir drop below the level of the clutch line outlet or you have just bought yourself a world of hassle.
The clutch pedal needs to be wedged to the floor for bleeding. A piece of 2x4 works fine. Don't be tempted to skip bleeding the clutch even though it is a royal PITA to get at the bleeder.
The wear sensors are not actually required, Many people don't re-install them in the pads and instead just wire them up to the suspension somewhere out of the way. I did not do this. Also, judging by the extremely low resistance through the sensors, I think you can probably just short the plug they attach to and eliminate them together, but I stress that I have not actually tried this myself and am merely guessing.
While the brake job is very simple and easy on these cars, it is definitely possible to botch it up if you are not careful. Here's a link to Pedro's site:

Thus ends my unsolicited advice - good luck!
