You really shouldn't experience any brightness/contrast issues due to scaling.
However, as a fellow 768p display owner, I recommend forcing different resolutions in different situations to see what works best for your AV setup. With a 768p set, games on the PS3 will generally output at 720p. My TV's scaler doesn't do so hot with upscaling from 720p to 768p, so I get some image bleeding. For content that allows it, I force the PS3 to output higher than 768p (uncheck the lower resolutions), since my TV does a much better job at downscaling than upscaling.
Play around with it. It's a pain at first, but you'll be satisfied with the results. Generally speaking, though, you'll only notice minor differences (if you notice any at all).
