Welcome. Seeing that its an 05, if it hasn't been done already I'd remove the TB and clean it inside and out, clean the MAF with approved MAF cleaner, and maybe think about plugs and wires since it just hit 100K. And don't use Platinum plugs. Copper or the stock irridiums are a must on these cars. And as you seem to know, premium fuel (91+) is a must as well.
Besides that, the only other things to look out for are wheel bearings/hubs, and the trans. If you haven't had the fluid changed recently, then now would be a good time to drop the pan, change the filter and refill. I can't recommend a flush as I don't know it's history and a flush often leads to a dead trans. soon after.
