I'm with you on the cables. Don't buy that gimmiky stuff at best buy.
The biggest thing to me about cable is that you want it to not add any appreciable resistance, otherwise you'll loose volume on the channels that have longer cable runs.
I just go to the local home depot/lowes and get generic speaker wire by the foot. I usually spring for between 12 gauge and 16 gauge and then cut it to length myself. Works excellent.
And bananna plugs are useful, but not required. I like them on the receiver end of my speaker wire, because thats where its harder to work with.
Good luck
