Lol it will be the best 3 years of your life mind! and cost-wise you can get a student loan that will cover that so worry about that later (9% on everything over 15k you earn or somthing)
As for Uni's
its good to get one that offers a sandwich year, takes an extra year but that year you in a related job getting good experience and getting paid quite well for it (and you still get your loan through)
a few courses i kno about are
Aerospace Engineering - probs best for you as lots on structures and propultion
Aerospace Systems Engineering - (what i'm doing, goes more into the systems and circuitry of the aircraft)
Aerospace Engineering with pilot studies - probs not suited for you as its trying to gear someone towards a pilot ect
Have a look at various courses and read all the moduals that you do and then what location you'll be in ect and want links they have to the industry
