I had previous experience with lowering and lifting vehicles, plus I watched the steeda vids and the fatguy vid too.
Do yourself a favor and after you pull the front shock-spring assembly, take it, along with the new springs to a local shop that has a floor mounted spring compressor. Trying to compress the springs on the bench is a pain. Also, on the rear you don't need to drop or lower the subframe, just pull one of the lower control arm bolts to gain enough clearance to pull the stock springs out.
BTW, Cdubya and myself are both local. I'm out west in North Olmsted, and he's out east somewhere.
