Nice budget :)... I'll put together a few recommendations then
It's worth reading this about 3D TVs. They are still first generation, so there are some trade offs. But that's the price of early adoption :)
It's getting the best press for 3D TVs. Panasonic is the only brand still pushing the plasma route, and it seems this technology is producing a great 3D picture - though potentially a little darker than other LCD brands. But as you're in a garage that will be OK. Really it's got everything you'd want build in - freesat, freeview HD, online services, DLNA networking and playback of music/video from USB/SD card. It's very, very cool.
You'll want a couple of extra glasses. They come in different sizes.
I have a much more modest Onkyo, the 606. Awesome sound. This is one of their flagship products. 9.2 surround. Networked. 220 watts, which is pretty loud. Multizone (3). You have 8 3D ready HDMI inputs, with one on the front which is very handy for making ad-hoc connections (eg phone, camera, etc). Very nice indeed.
Very aspirational. Reason for suggestion: What Hi-Fi review: http://www.whathifi.com/review/bw-cm9-theatre
You'll be needing a nice 3D blu-ray player. I actually rate a PS3 pretty highly for blu-ray output, but you'll want something to match the level of the rest of the kit.
You might as well get a PS3. 3D games!
You'll need a universal remote, otherwise... things will get complicated. I have the model below this. With all this kit it's worth investing a bit more for this one. A little tricky to set up, but you only need to do it once then it works like a dream. The 1100 is above this, but I don't really understand the value (it costs almost as much as an iPad). The 900 has RF - which means you get a separate 'IR blaster' that sends the signals so you don't need to point the remote.
FOR AMUSEMENT VALUE ONLY. Read the reviews. Very funny. (Cables are important, these are probably not required, the price has come up wrong, it's missing a digit at the front!...)
if it's available in your country..nothing is better than this one..http://www.bestbuy.com/site/Mitsubishi+-+Home+Cinema+/+60%22+Class+/+1080p+/+60Hz+/+3D+DLP+HDTV/9966999.p?id=1218202944577&skuId=9966999
