Rick gave you good advice on those shocks. The hardest part is getting the seat out. One thing that I would add is to soak the bolts on the bottom with liquid wrench real good before doing the job. I soaked mine for about a week before I did my job. Although that Might be excessive I would spray them down when I got home at night. You dont want to brake those bolts. OTher than that it was a simple enough job. I used Blistiens and am satisfied with the ride.
also while your there it may be a good time to change the rear brakes if needed. At least check the parking brake adjustment. and clean out all of the water drains
