Well... I think you should have bought the R11 complete set at level 32, and it's still not a bad idea. (I have that set and still break it out when I want a bit more of a challenge than top level clubs provide.) The driver, 3wd, and irons will easily take you to level 59 (and beyond) when the high loft irons become available. (Sell the hybrid; it's not needed at this point.)
Get the taylormade wedges when you hit level 39. Personally would go with 64, 60 and 54 degree.
Biggest difference in putter at lower levels is that you get one extra (short range) meter distance. In other words, might want to wait on that until you feel the need for something to finesse those shorter putts with.
Checked out your profile page, looks like you've been hooked. Welcome to the frustration of WGT.
