2001 Town and Counrtry Ball Joint Replacement Help

I've got a 2001 Chrysler Town and Country with 150,000 miles on it and bad ball joints. Does anyone have any recommendations on replacement? I have access to a shop that can press out the old ones and new ones in, but am I better off replacing the entire lower control arm thus replacing all the bushings given my mileage? Any advice on doing the job?
