I agree with Bart, the KISS should definitely be implimented here, Keep It Simple Stupid ;-)
Far too many times I have tried to fix TOO much and ended up having worse problems down the road with what I was trying to avoid. Keep it as stock as possible.
Just like Bart said I would replace LCA and bushing and then go to a place that does do the laser alignment. My gut feeling is that you will be good to go after that :-)
