I did the installation myself on the '07, and it like Neal said. If you order the tour pak, you are just getting a piece of luggage. You need the rack to mount it onto, and the docking kit to mount the rack onto the bike.
I too installed my Tour Pak. I bought the TP along with the mounting kit and the docking kit. All together it was about $850.00
I cut holes in the rubber plugs before I ran the docking kit through them. This way I have the plugs, but with the chrome dock tube through it.
The kit went on great and without any problems. Everything to do the install comes in the three pieces.
For those of use that carry a bit of extra weight and don't have a skinny wife, Kuryakan has a relocation mount that allows for the TP to be put back about another three inches. I bought this and my wife now has loads of room between us when we ride. She always felt like she was sliding forward as well. Before I bought the relocation mount, I drilled an extra set of holes in the chrome mounting rack plate and then moved the TP back about 1.25". That was better, but not as good as the new relocation mount. I think it was about $125 for the new mount which is nothing more than a "U" shaped chrome tube with eight holes in it.
Good luck with the kit, it's really quite easy.
