Definitely get a 100 foot spool of 14 gauge wire.

I think the M60's are wonderful, and I'm sure you will enjoy them and the VaSSallo finish.

Since you are using the system half the time for games and movies, a sub would be a meaningful addition. I don't think that a sub is going to be any more annoying to your neighbors than the M60's; it all depends on volume.

Enjoy your journey!
