Pretty much what CTS said, kings links is your best bet, try out some second hand clubs and see what you like! You might also be able to get some decent game improvement irons if you shop around, worth speaking to someone at one of the golf shops about the options.
Although a couple of lessons are the best/quickest way to improve, kings links is ok for lessons but I've been out to the Paul Lawrie Golf Centre for a couple of lessons and they were fantastic, pretty reasonably priced considering the quality of the lessons too. Half an hour and I could actually putt and have a reasonable idea where it was going to go!
