about to put re6200 5.5 ed kit on... upgrades?

I finally got around to ordering the rest of my tires and i got enough money set aside to order the SYE/DS and shim as soon as i put the kit on.

I have all componets for re6200 (http://www.rubiconexpress.com/dynamic/mainpage.asp?folderid=185) and monotube shocks.

i was wondering if i should upgrade to adj. trackbar or adj. front uppers or lowers?

my jeep will be mostly unloaded... only a yakima roofrack with a 33x12 mickey thompson on top.

and other recommended upgrades before i start bolting stuff on?

That kit already comes with an adjustable track bar so your good there. I would recommend upgrading to adjustable uppers and lowers. With the adjustables you can dial in a good pinion angle and it just makes things so much easier.
