Regarding brake bleeders: You can do it perfectly with an under $10 catch bottle and tube if you have a helper to pump the pedal. The basic rule is to never have the bleeder valve open when there is no pressure on the brake pedal or air may be sucked back into the caliper. It is convenient, but not required to switch colors on brake fluid to confirm that you are getting new fluid. Of course, ATE super blue fluid is not quite as common as all the other clear fluids.

So-called one-man systems are nice although I don't find them good enough if you are trying to fill up and de-bubble a new caliper; In that case a good foot on the pedal gets the last bubbles out. The "eezibleed" kit you mentioned seems more popular in the UK, and some versions seem to operate using pressure from the spare tire. Most BMW folks (me included) seem happy with the Motive pressure bleeder, also sold under Bavarian Autosport's name. I would stay away from vacuum-types.
