It's definately possible to do it yourself, the only reason I had a shop do it was that there is over a foot of snow on the ground and no garage. It will most likely take you a weekend to do the lift with drop brackets by yourself. You will need to get new axle seals because you will have to take it out. The brackets alone were $350 with a $100 return on the core at www.Darlington_offroad.com Make sure you get the one with the crossmember drop bracket as well (most expensive on his site)

I would suggest getting the spring spacer if you plan on dropping the diff, you will be very happy with the results! And its only like $100 more for the extra 1". I think you will also need new rear shocks with this setup though, fronts will be fine, I have the Bilstein part #'s in my profile. The ones I got are supposedley a tad bit long and the shop said I could possibly loose a spring but I went wheeling and it didn't even hiccup. I like the feel of the rear shocks I got, but my fronts seem a little soft/bouncey.

I also got 2" rear bump stop extensions, no need for brakeline extension.
