Yeah, I'm helping you out with that axle, if you want to cross ship, I'll send it out like Wednesday.
Rear wiper - I've got a clean hatch with no wiper on it, I'd trade you even up, but you'd have to come here to get it.
Rear brakes - Screw drums - unless you like them. Get my rear discs
If you like the rear drums, see if you can't find some drums from an early HF CRX - they're aluminum with steel friction inserts, so they're lighter and cool off faster.
Alignment - The only spec that's adjustable on the front is toe... none are adjustable on the rears. Check your trailing arm bushings, if they're good, and if your rears are off a bit on camber, put a couple washers behind the two bolts that hold the rear trailing arm's compensator to get it as close as you can. For the front, You go camber out a bit when you lower the car, but the funny tire wear comes from Toe adjustments being out, because the tires "scrub" instead of rolling.
Oil light - Install an oil pressure gauge, don't trust that light. I've got a D-series oil pump, if you need one, unless your oil dipstick goes in through the pump, then I can't help you with that.
Booster problems - Just do a booster delete... The car's not that heavy.
I have the largest OEM ED Civic Master Cylinder, sitting around somewhere, but I'd have to dig it out. It's 15/16", from a Civic EX. (You have an ED CRX, not an EF, in case you didn't know.) The 'teg's MC is only 1", and you'd have to use the booster and MC.
