I've just ordered 4 caliper rebuild kits and new brake lines (through Pelican

) after finding that my 2 ton 4x4 pulls up faster than my 69T. A good close inspection indicates that it has been a very long time (if at all) since these items were serviced. So my questions start like this:
Do I drain all the brake fluid from the system before I begin?
Are there any special tools required to rebuild the front S alloy callipers and rear M's?
What are the respective differences between the "power bleeders" on the market, and do I need one? (I have a wife

)
Should I have read Waynes book before posting?
Are Pagid "blue" pads a suitable replacement for street use?
Can anybody offer me any other pointers before I start?
Thanks Everyone
