Starting from scratch

I just bought a new house, with the living room measuring 17'x17 also connecting to foyer and bar window to kitchen, all floors being tiled.

It is pre-wired for a 5.1 system in the living room, as well as an outdoor speaker, and I have a Sony Bravia KDL 46EX500 (wall mounted). (not Internet TV nor 3D). HDMI connects tv to "will be" receiver.

Primary use is TV-sports etc, movies, Wii, two zone indoor/ outdoor for parties, BBQ, etc. No serious requirements on HUGE volume output. No real gaming requirements needed. However, Netflix, etc IS needed
Inputs are Cablebox, Wii, DVD/blueray...pretty standard stuff.

Looking to spend <$1000 preferably and need the following:

Receiver unit (2 zone for indoor/outdoor options) does this mean 7.1 is needed?
DVD/blueray player
(one of which needs wireless Internet connectivity as I understand it).
speaker set-up (white "preferred" by the fiancé)
on wall tilting option mounts
outdoor speaker (1 prewired, more MAY be added in future)
what else am I missing?
a control all remote will be in the near future if needed.

I'm totally new to this so any and all recommendations, links, advice, or other input is more than welcome. I'm starting to get a grasp on what is needed but fall short on what to get.

Thanks.

Thanks for the replies. I've pretty much thrown the white speakers out the window as they seem to be either very low end, or pretty high end.

I'm continuing to shop all of your recommendations up to this point.

Any more insight is always welcome.

I am also going to run additional wiring for the outdoor speakers. The solo speaker being problematic, never crossed my mind. I plan on adding a tv to the back porch anyways, so that will get that out of the way. Thanks for the insight.
