Fantastic! Well, let me suggest something with a projector and screen combination. Research and get a projector first. Find the one that most appeals to you (if you can audition as many as you can in person). Then after you've established and bought what you wanted, then play with the projector image and throw distance to see the best balance between quality/size/brightness. After that, order the proper size screen.
As for speakers? One of the greatest and most bang for the buck solutions is online direct. There are PLENTY of internet direct companies that make utterly fantastic speakers for their price. You will have to research them individually to see which speakers sound like what and cater them to your own preference, but another great thing is pretty much all of them have 30-45 day money back guarantees (less shipping). So if you find out it's not quite the right speaker for you, you send it back and all your out is shipping cost. Again, just do a bit of research to even possibly avoid even that shipping cost.
SVSound.com, Axiomaudio.com, AV123.com, Aperionaudio.com, Elementaldesigns.com, Hsuresearch.com, and Ascendaudio.com a handful that come to mind. Check each of those websites out and the reviews (user reviews as well) and see which one fits your needs.
