Help with understanding my forks (Revs 09 air u-turn)

I'm going to be servicing my forks (with some help from bro) and I don't really understand the ins and outs of my fork. I'm thinking about purchasing the refresh kit from TFT ( http://www.tftunedshox.com/Catalogue/Sh ... tion-Parts ) and this as I understand, is for the damper and lower service? Then I was also contemplating getting the service kit as well while we were doing them (on the same link further down).
Now I don't really understand what each part of the fork does and therefore don't know whether it's worth doing both. Any help would be greatly appreciated.
Thanks!
