On my 90 with 6.5" the ebrake cables were tight and limited flex in back.
Currently I have no ebrake, but I plan on fixing it using 2 of the longer cables from a 97+. I have one of them now(came with my 8.25), and it should work fine with some bracket modification.
You definitly will need new hydro brake lines front and rear, YJ lines worked great for me, I still had to relocated the front hard lines though. At full flex and turn they are starting to get a little tight, but I have tweaked my suspension and get more flex than most short arm setups not using DBs.
Make sure whan you check the legnth of lines, you take into account not just wheel travel but turning as well.
If you're dead set on the RC kit, you may want to consider using a better adjustable trackbar. I had a RC trackbar once...It bent under mild wheeling conditions!!! That was after eating up 2 rod ends in a month!!! They MAY have redesigned since then (doubtful), RC parts don't have near the beef the others do, but you get what you pay for.
As far as steering, you could use the drop pitman arm to help angles, but you will get bumpsteer. The trackbar and draglink need to be paralell, and about the same legnth. Using the drop pitman arm will throw the angle off. Not to mention the added stress it adds to the already weak steering box mount! Search on here for steering upgrades!
I will finish my rambeling by saying if your only going to run 32s, you would be much better off with 4.5"! Those extra 2" can cost a lot! On 4.5 you shouldn't need to worry about steering, shortarms, ebrake cables, and when I was at 4.5 I didn't even need an SYE!
If you go 35s, you will need to replace axles too, at least the D35 if you haven't already.
