Congrats on the purchase..
We have a swp '14 XT also, and couldn't be happier.
Couple things. The sports grill is expensive, and I wasn't really sold on the look, so I plastidipped the chrome wings in the oem grill, and the chrome fog light surrounds, and it looks 10x better. Although mine doesn't have all the chrome around the windows like the limited does.
I went with Rally Armor. I've never had an issue with them,on any vehicle, even on the CRSOPNR, which sees heavier than normal gravel use.
Don't get weathertechs. on the 2014 Forester the weathertechs don't cover behind the gas pedal, so a lot of gravel/snow/water/etc, will fall between the floormats and firewall. I went with Husky liners.
I did the interior LED swap through Diode, and happy with them so far. The only thing I don't like, is the hatch light (or lack of usable light). but that's a subaru design issue more than anything.
I almost ordered the LED Accent lights, just haven't got around to it yet, and I never noticed those mirror piece before.
I wasn't sold on the CVT initially, but after driving it for 4 months, I wouldn't have it any other way. SI drive makes up for it.
