1) Not 100% sure, but it sounds like your rear window regulators are bad, a common E39 problem (my assumption since I didn't notice your auto type). See bmwtips.com and 540i6.com "They all do that!"
2) Those cables route power forward from your battery to the engine (starter, alternator signal back to battery, etc). I HIGHLY recommend against messing with those whatsoever. Do not touch them. If you have an E39, there is a nice little white connection block located above the trunk-mounted battery that is IDEAL for connecting a sub/amp. Once again, see BMWtips.com: subwoofer installation tip.
Sorry, I cannot help you with #3. Good luck!
