I think Rick will continue to struggle with his conscience/compassion towards the living. He crossed the line at the bar when he killed the living to save the living. His wife will continue to push him to take out Shane because she doesn't want the conflict about the baby (which we all know is Shane's).
The farm will be over-run and some conflict with the other group of survivors will have to take place. They'll get some information from the kid with the bum leg.
The redneck is continuing to distance himself from the group, his ear collection will eventually get the better of him and he will be a walker from secondary contact...
