From all of the articles I have read concerning verizon FiOS, they install a grey plastic box

on the side of you house for the outside maintenance. Then, there is a battery backup that is placed on the inside of the house,

Then just connect to your router.
Verizon does offer to set up your network, though you can request to have them leave it alone(if you know what you're doing). I've had friends in connecticut receive FiOS already. You don't need to install anything special into your computer if you've already had a previous broadband connection.
I've posted these links in the past, but I'll post them again here for posterity. Very useful to know exactly what you're getting yourself into.
