Same questions I had a few months ago. I agree with the others, definately go with an adjustable panhard bar, and probably want shocks too. Once I lowered my car and let it settle, my rear end was shifted over 11/16", which is almost 3/4", and was easily visible with the naked eye. I installed an adjustable panhard bar, just installed a set of Roush Stage 3 Rear shocks (waiting on the fronts) and the ride is better. As far as the install goes, make sure you have some spring compressors and an impact gun really helps. The removal/re-installation is very easy and straight forward. You can expect to spend 2 -3 hours doing this. Hope everything works out well!
