182_Blue is spot on, chose the Highline computer as your 1st extra, (and then armrest as your 2nd).
Xenons are excellent if you do much night driving, DSG if you want a bit more acceleration and want the ability to tour long distance in comfort, as well as town driving in ease.
Cruise can be retro fitted for about £150.
You can get rear tinted glass, an iPod adapter in the armrest, 18" wheels, which do look better but not essential as the 17's give the same grip, weigh less and give a smoother ride.
You will love the MK5 GTI, I do
