Well, one of the pots on my guitar is now loose. Any way to fix it myself? Or do I have to take it to the shop?

pull off the knob and get a wrench that will fit the nut around the pot shaft, grab the bottom of the pot and tighten the nut with the wrench.
Ibanez -> Peavey -> Eardrums

Apparently I'm on some list of people to listen to..?

^ Yep, just don't let the pot spin because you might rip wiring loose.
