You really should be looking at the AVR's such as the Anthem MRX, NAD T7xx or similar for movies, or if budget allows go with a pre-processor and amps. A simpler integrated just won't be outputting a true LFE signal, as it can't decode it.
You're getting a fantastic bargain on those speakers! They're really good, and in high demand so getting a discount like that is no small thing.
