Wedge-wise, the wedges you have are fine until you hit L76 for the high level brothers, I'd take the L59 G20s at 2,195, these can go to Legend and will be fine until you hit L83 (hi-level G20s), 85 (mid-level Nike V-Forgeds), or 90 (high level R11s). Seeing a starter wood in the profile, a better wood is in order. A cheap and very good one is the G20 3W @L58, only costs 495c and could be the last wood until you want to save for better stuff.
As for the putter, I'd just stay with the current one until you can get more credits for the MAX Control Master one for 2500c.
