dunno about some of them, but some suggestions:
1 and 2) maybe a fluid change would help. the dealer probably wont do it since they believe its a life time fill.
3) i dunno, i would prefer no abs anyway. i believe there is an abs sensor, is your abs light on? mine came on one winter when ice froze over it. when it thawed, it was fine (just my experience, i know that wasnt ure situation, maybe a rock or debris?)
4) velocity? like its not throwing out as much air as it once did?
5) they should definatly fix that.
