New to the game, looking for help on this system

Being new to this, I need some help with interconnects, video/audio & speaker cables that might match this beginners, somewhat outdated system. It is being used mainly for home theatre use vs music, but both are important. I'll probably post this on VideoGon also for the video end, but all comments welcome.

Acurus A125x5
Lexicon DC-1 with all firmware upgrades
NHT 6.2 Ci (front)
NHT SuperZero(rear surround)
NHT SW2Si

Kenwood Sovereign (400 disk with DcDi by Faroudja)
Mitsubishi Diamond 65" with 9"CRTs(2004 model)
DVR with HD
SVHS for the kids stuff

Thanks ahead of time!
