I know the feeling! I had a 4000D sitting in my basement for a long time and after lurking for awhile, I finally felt the urge a couple months ago to get it up and working. I got a 4000T off of Ebay and have a pretty nice 2000 system on the way as well.
I don't have an RGB monitor either, and I've noticed some issues hooking my 4000T up to my LCD monitor (although, strangely, not my 4000D). I'm curious to see the answers to your questions, though, since I'm going through some of the same stuff right now.
