Thats why i want to know if you need something ealse than the hdmi and plasma tv to get the best picture possible

Suggestion:

Plasmas are better than LCD's for games.

What you can do is find the right calibration numbers for your plasma and adjust the color settings accordingly. This site explains why it's a good idea to calibrate your TV http://www.tomsguide.com/us/hdtv-calibration-isf,review-1190.html

You should be able to find calibrations numbers on the net especially if it's a popular brand TV.
