Welcome SL
It sounds like you are looking for a giant killing system at a budget price, and you've come to the right place for as many opinions as we have board participants.
I'd recommend a digitally amplified Panasonic XR50 or 55 which you can pick up for under $300. I'd get an Oppo Digital - OPDV971H DVD player for under $200. I'd go with the VP100 center, a pair of M3Tis for the front L/R and a pair of Bic Acoustech Ht-63 Surround Speakers for about $180.00/pair. I'd check your local classifieds for a used subwoofer which you can demo and make sure works without making flatulating noises. A nice used Velodyne CHT10 for about $150 would be a great addition that system.
Good luck and welcome!!
