welcome to the forum!
yes, your car is the mk3 and 2011 onwards parts will fit your car.
getting new parts will be very expensive. any decent bodyshop will be able to fit the parts without issues.
if you are going the 2nd hand parts route you might even find them in the same colour as your car so will save money in painting costs.
the ebay item has been removed so cant comment on that. you can get all the parts cheap off ebay if you are patient.
most of the stuff is easy enough to fit yourself to be honest. all you need is a few diy skills.
if you get stuck then there are plenty of people on here who will help and advise you.
