I don't think you can go wrong with the 4" lift and the shackle flip. Ride will improve and the body to tire clearance will improve too. Although with the 2.5" spring out back combined with the shackle flip, you might get a little more than 4" out of it. See DirtyLarry's thread in the 4x4 section on his ORD flip kit install. He had re-arched stock springs and an add a leaf that made the rear sit higher than the front after the flip was installed. He had to take the add a leaf out.

Cutting can be done and still look ok. You can always go back and reinforce the cut sheetmetal by welding in 1/4" round bar to the edge where it was cut. the round bar won't be as easy to catch as the cut sheetmetal.

I've got a couple of pics from CK5 that maps out the cutting of the fenders/quarters for use with large tires. They are too big to post here, but if you want them I can email them to you.
