Those picture and brightness settings seem reasonable based on what I've found in tuning with Avia, though it's worth keeping in mind that what your settings should be depends highly on your room lighting. That said, AFAIK the rule of thumb is to keep the picture setting below 32 and if you still can't get your whites to look truly white even with that then you should look into getting your room dimmer instead.

Color and hue should remain right in the middle with this set, though you'll have some overemphasis in the reds (aka "red push"). I was able to correct this on my set in the service menus but that's probably beyond what you're willing to do.
Personally, I use a sharpness up 12 notches from the left (13/64?). As Avia suggested, it seems rather soft after doing that initially, but I do indeed notice fine detail with the lower setting now that I could not with the default settings. Also make sure to turn off ClearEdge VM for the same reason.
Last thing would be the DRC settings, which only apply to non-HD feeds. The DRC settings seem to be a pretty personal thing, but I've personally found that keeping them down to the lower end (the default 25 /1 setting for reality / clarity I find to be fine) is better than the higher end, again for the same reason of wanting to avoid having sharpness too high.
