You might want to look into wiring the house for ethernet, since almost everything now can utilize an internet connection (TV, Xbox, streaming boxes, etc.) I recently did this from the office into my room and I'm getting the full speed we pay for. I use the spare powerline boxes for when friends are over.
If you do go wireless though, I'd probably opt for an internal card with an external antenna, depending on how far you are from the wireless router.
