I use a 3D Tv myself. It's not the same TV, nor is it the same size, but I can offer the advice that there is no "right" settings. It depends on your personal preference, distance from the screen, screen size etc. You may want to play around with the settings and find out what feels correct for your particular setup.
Gran-turismo.com offers this as a suggested starting point for in-game 3D settings though. Might be a good place to start.
