The trailing arms and coils are actually a very good setup. There are a few guys over in the Racing and High Performance section running pretty quick with them. Of course they need to be in good condition and it would be a good idea to reinforce them. As fro the differential, you will need to have the housing narrowed and buy a set of aftermarket axles. This is not something the average guy can go in his garage. You need the proper jigs and adequate welder. Then the housing needs to be straightened after all the brackets are welded on.
