Wall mounting is fine, my VP150 Center and QS8's are wall and ceiling mounted respectively. Although I use Axiom's Full Metal Bracket, which I quite like (although it's angle isn't completely accurate, so my VP150 is off a bit).

As for cabling, I like 12 gauge. I ordered it in 175 feet bulk from Axiom, works lovely. Very solid cable. I have runs varying from 6 feet to 45 feet (up wall and across ceiling). Good stuff all around.
