what else should i have???

currently setting up HT...sort of a beginner, so need help. Looking for: 1. pre/pro (<$5000) 2. DVD (<2000) 3. sub (<2000) 4. interconnects/cables (total < 1000) currently have: 1. Bolender Grabener 520 and 220 (Hybrid Planar Magnetic) fronts and center, respectively. 2. Citation 7.3 dipole surround 3. Nakamichi PA-1 5 ch. amp. Thanks for everybody's input
You now need lots and lots of movies !!! And popcorn.
Just added Lexicon MC-1, Velodyne HGS-15 and Pioneer elite dv09 to my system...I think I'll become a couch potato now!! Any thoughts on interconnects/cables, anyone?????
