Sounds like you might just need to attack it with some switch cleaner spray as far as the crackly pots are concerned. Simply spray liberally around the control pot then spin the pot around vigourously for 30 seconds or so. Should sort it right out.

Depending on how dirty it is, it may sort out your other problem too.
