The first things i would buy, and i did, were wedges, and the ones you have listed are very good for that level. They were the Z-Satins back in the day, now just basically a new name. They will serve you well.
Next up, The Daytona Rossa putter at L55 i believe...that was my next purchase....it was and IMO the steal of the pro shop at i think 750 credits.....pretty much every Tour Legend or Champion here had that putter in their bag at one time....i still do. It works well for ding and off-ding styles both.
Any other clubs you really don't need til you reach Master, where you start hitting lots farther back...just a waste of your money until then.
That was the advice i got 5 or 6 years ago, and i still believe it to be true.
But is has been awhile since i was at your level, maybe others can give you better advice.
