Bedroom tv question

Thought I'd save a few bucks and get a nice little TV at Costco for the bedroom. Had other places I could put those dollars. But now I'm wondering, is everything prewired for the TV in the bedroom? Cable hook ups, electrical, mounting bracket, straps? Not seeing it in the brochure. Wondering if I need to make a quick addition to the order. BH3160, BTW.

Thanks,

Rich
