The Edina GC may not be the biggest store, but I think they have the best selection. If you go there, ask for Jingle (Joe) if he's there. Good friend/bandmate of mine
Roseville is good too though, ask for Chu. He's awesome.
Or if you venture out to Maple Grove, check out the GC. Ask for Zack, another bandmate.
EDIT
I didn't see the part about checking out light and pro audio... definitely go to Edina and talk to Joe. He's very good with pro audio!
