1) Yes, it should be more than capable.
2) The main difference is that the non Deluxe version doesn't have SLI support. So if you were looking to add a second 480 at a later date you couldn't with this motherboard, however if you were looking to add a second 480 you'd also need a more powerful PSU. Other differences are minimal, however if I were to upgrade MoBo to SLI compatible I'd probably just get the PRO version rather than the Deluxe.
As for swapping out components:
GPU is fine
CPU and Mobo are fine, however if you're going to choose those 2 then get this:
http://www.overclockers.co.uk/showproduct.php?prodid=BU-014-OP&groupid=701&catid=6&subcat=1858 as it's exactly the same apart from with some off
SSD: I'd probably wait (in fact I am) until the c400 comes out in a few weeks (can't remember the release date) but it will be faster and probably cheaper.
PSU: This:

Case/CPU Cooler - Fine
RAM: Not sure if you need 8GB, if you have a good reason for getting it then yes, if you just threw it in there because you thought it was a good idea, then 4GB is fine for gaming.
HDD:
http://www.overclockers.co.uk/showproduct.php?prodid=HD-067-HI&groupid=701&catid=14&subcat=1279 Minimal difference, this one's on offer atm (one of the three 1TB drives out of the Samsung F3 the Hitachi I've put up and the one you have tend to be on offer each week, depending when you order, there's basically no difference between them!)
Optical Drive:

No real difference between the two, saves you some money
