L59 G20s will be a great choice that many (if not most) top players used well in to Legend with their high trajectory.
Wedge wise I would look at those L40s Pings considering the 100, 75 and 50 yard options if it were me. By the time you throw in the punching capability of your PW and those three wedges as well you will have several good basic shots. EDIT: Don't forget topspin options to:)
Remember to learn punches and full shots (look in the forum) throughout the range of those wedges. E.G my CG64 is rated at 60 full shot and 50 punched, but will go 32 yards full shot FBS and 22 yards punched at 60%.......... massage around that and understand flops, pitching and chips and you are well on the way to a whole array of capable shots.
I would also look at putters. For me (so personal I know) the L35 Ghost is a little gem that will see you through to Legend by which time you will know more (ding or miss ding is a basic need to know), and can choose your final solution. In all honesty I do not rate the L19 spider although I don't think it quite as bad as some say.
EDIT: Alosso below speaks sense as usual. In the end your choice :) I suggested the pings mainly because they are outstanding value, and will do the job well enough until replaced. I think 3 are ideal and at that price...your credits.
