Let me start off by saying I'm no expert.....
Yea, the concept of wireless speakers sound nice, but I wouldnt do that either. Wireless speakers are more convenient tho for it having no wires. Imma show u the setup I got from Amazon couple of years ago....While I'm getting this together, I recommend Amazon, Newegg or Tigerdirect for good prices on HDTV's.
Looking at your price range, I would suggest a home theatre all in one package.
This is some of my invoice from 2008: I woulda added links but some of thes items are no longer available.
These were 2008 prices, they should be cheaper now. And this is a setup where everything was separate, no all in one.
1 of: Nintendo Wii Component Av Game Cable
Sold by: BargainCell (seller profile)
$3.09
If u dont have component cables for the Wii, grab some. U can tell the difference when using an HDTV and u use anything less than component cables for game systems, cable boxes, etc.

1 of: HDTrinity 2m (6.5ft) Gold Series Premium HDMI Cable 1.3b Category 2 Certified 10.2Gbps

I tried to be extra smart with the lengths for the HDMI, and wound up needing longer ones. Get 6ft or longer.
1 of: Samsung LN46A550 46-Inch 1080p LCD HDTV
Sold by: Amazon.com, LLC
$1,439.04
I included this but thats not the price for 2010. U can find a 46 inch LCD for right at or under $900. LED's....I'm not sold on them yet, something about Local Dimming vs. Edge Lit; I need to research it more.
1 of: Pyramid RSW1250 50' Foot 12 Gauge Insulated Speaker Wire
Sold by: Etronics (seller profile)
$13.45
If using wired speakers, the gauge is important. The lower the better.
1 of: Polk Audio RM6750 5.1 Channel Home Theater Speaker System (Set of Six, Black)
Sold by: WholeSaleAV (seller profile)
$228.23
Now, these speakers dont have any tall ones. The rear ones would need to be either on a stand or mounted to the wall. Again, these prices are from 2008. The tallest speaker is gonna be the subwoofer. I dont think u can find a small one, not sure.

1 of: ONKYO TX-SR606 7.1 Channel Home Theater Receiver - Silver
Sold by: 6ave (seller profile)
$379.86
**This reciever has HDMI connections to make it easier and cleaner for installation, and to have the best connection possible....***
I starred 2 items cuz....I had everything connected to the reciever by HDMI. I thought having a receiver with HDMI was the best thing. It wasnt. After a year, the HDMI started tripping out on the reciever. I kept getting "Searching for Signal" messages on the TV when going from a standard to a HD source. It was doing this before but not as bad.
For sounds to come thru my reciever, I grabbed the fiber optical cable and use that for sound for the cable box-to-reciever, and some regular audio cables for the game systems connected to the TV. I use the HDMI for picture only.
