Luke,
The above reply is excellent comprehensive advice. If you take it seriously it will stand you in good stead.
The only item that I would add is this - many companies value some form of service to the community. Charity work or another form of volunteerism. Not only would this sort of activity help you become a more rounded person, it may help you achieve your goals. Find out what charities your target company supports. If you also believe that they are a worthwhile endeavor, then that may give you some direction as to which one to join.
This will look good on a CV or application form, and you'll be a better person for doing it.
Good luck.
