He goes by JPi1 here on the forum.
JPI will get you anything you need. With a JKU Rubicon, you already have decent rails, though more coverage is always better. I would start with skid plates. EVO makes a 3 piece set for the JKU that covers most of the vital areas, it's around $400 for the parts.
I would also advise diff covers. The factory ones have a bad habit of peeling off on rocks which can ruin your day.
I had the above installed by JPI as my next mod after my lift, but I think skids are a good first mod so you can wheel it right away with less of a chance of breaking things.
Mods I got in orders:
Wheels -- My biggest mistake. Got 33's because I didn't have a lift yet. Should've waited. Now saving up for 35's.
Lift + front driveshaft + Ace and Rubi rails
EVO 3 piece skid set
Front axle swap to a Rubi D44 + sleeve and gussets (you obviously don't need this)
Synergy tie rod - Stock one bends easily
