I would pick the new Samsung 56" 1080p LED DLP model which is just now arriving in the stores. In any case you want a full 1080p display 1920x1080 since with the much smaller pixels in a 1080p model some of the other effects you mentioned are not at alll noticable.
just in case check out the make/models your are interested in at your viewing distance in the stores to see if any of the effects you are concerned are present since what is a problem in one make/model may not be a problem in another make/model due to differences in the internal firmware as well of course for diferentn technologies.
