Best to download the AVS HD709 disc* and just set up the basic controls for brightness and contrast. IMHO the sharpness and detail enhance should be set to zero as they cause ringing and other artifacts with motion, but some like to crank them up (each to their own I suppose).
Stick with HDMI 'Normal' rather than the 'Enhanced' that some use as it doesn't really gain anything and you just have to change the contrast and brightness settings to correct (which otherwise will probably be spot on at '0' for both).
Try 6500K colour temp in 'Custom colour temperature'. Gamma is room and user dependant, but as a starting point try a custom gamma with it set to 2.3 (which will actually measure below this figure anyway).
Don't even attempt to adjust the RGB cuts or gains in the custom colour temp menu if you haven't got a meter. Though if you find the colours a bit too saturated you can try just lowering the main colour control, though this isn't really a 'correction' in calibration terms (since it's just reducing the luminance of the colours not the saturation), but subjectively you might find it better.
Best of luck and enjoy your new 'toy'.
