I was going to buy the flares from JustForJeeps.com, but actually ended up getting them from a forum member who purchased but never used (were still in packaging!).
As for the other parts: I've been debating it - painting it all out will make it fairly identical to an Overland/Altitude. On the other hand, all those extra parts, their price, and paint costs adds up significantly.
2014 Overland Paintable Wheel Flares $281.12
5JQ75TZZAA Left Front Wheel Flare
5JQ76TZZAA Right Front Wheel Flare
5JQ77TZZAA Left Rear Door Wheel Flare
5JQ78TZZAA Right Rear Door Wheel Flare
5JQ79TZZAA Left Rear Quarter Panel Wheel Flare
5JQ80TZZAA Right Rear Quarter Panel Wheel Flare
2014 Overland Paintable Body Parts
1WL30TZZAC Front Lower Bumper Cover $237.60
1VQ68TZZAA Rear Lower Bumper Cover $188.10
5PU65TZZAB Left Rocker Molding $135.00
5PU66TZZAB Right Rocker Molding $115.20
And that's the cost w/o paint
Those lower area's are also really hot spots for dirt/debris/chips - so part of me is thinking I may just leave them.
My new headlights are set to be here next week, so I will pop the color matched flares on maybe the following week-end. I'll toss some pics up and see how it all looks.
For the antenna, I know a handful of forum members have purchased these from Amazon:
