I just had a Centerforce put in about a week ago. It is sooo much better than stock! After shopping around I ended up getting it from car-stuff.com. To get the price down I had to mention that some other sites had it for less. I think they knocked off maybe $25. Some of the other places such as AC and 4x4rockshop had to either order it or drop ship. I needed it right away since my truck was already at the dealership, so that is primarily why I chose car-stuff. I think the price at most of the sites were about the same. Be sure you give them the correct part number (6 cyl vs. 4 cyl).
I didn't really need a new clutch so I don't know what else you may need. My transmission went out (no 1st gear). I was 2 months shy of my 100,000 miles/72 month extended warranty so it was covered. Since they were going to have the transmission out anyway, they said they would install the new clutch for $100. I am at about 60,000 miles so I figured I will need a new clutch at some point since I offroad quite a bit.
The dealership replaced the transmission, installed the Centerforce, replaced the rear main seal, wheel bearings, got the rear window to go up/down faster (regulator didn't need to be replaced), new windshield wipers, and replaced a couple bolts to the roof rack that I had lost. I had them check for an exhaust manifold leak (none) and they had indicated SES light intermittently goes on (which it doesn't) so they could check everything else. The total cost to me was $169.50. It was $100 for labor for the clutch and $69.50 for the warranty deductible. They also paid $30/day for a loaner car. I chose an '08 Fronty pickup so I ended up paying something like $7/day for the upgrade. It took them about 10 days to do the repair, but part of that was because they agreed to drag their heels in getting it done to allow me time to get the clutch. The only thing they wouldn't do is install my clutch interlock bypass switch because they said it was unsafe.
I sure am glad I got that extended warranty!
