re: Poker & Multi tabling software/ MT site question.
I've never used table management software because I always tiled. I have a triple-monitor rig, all three running 1920x1200, so had no trouble tiling 16 tables across two monitors when I used to multi-table on FT, and running HEM and browser on the 3rd.
If I were to stack or cascade though, I would definitely be looking for something to help. I had considered TableNinja but I hear a lot of complaints with performance when you get a lot of tables going and are running a tracker+HUD.
I've heard a lot of good things about Hjalper
over the last couple years -- it was actually originally written to support multi-tabling with an Xbox controller, but supports keyboard+mouse hotkeys too. Supposedly much less resource-intensive than TN. It's Stars only, however.
