I wouldn't buy a driver yet. Buy a good 3-Wood. It's good from the tees until Master level, good as a fairway wood long after reaching Master, and very useful for long punch shots from the rough. When I reached L48, I got the Mizuno ST200 (235 yards, 4.0 meter, 5.0 forgiveness.) Another good one would be the L51 Callaway Rogue ST LS (235 yards, 4.4 meter, 4.0 forgiveness,) The Callaway is cheaper by a few hundred credits. If I were you, I'd probably get the L51 Callaway and put the extra credits toward wedges. I already had some decent wedges by the time I got a good 3-wood. Cheaper route would be to buy the L46 MAX Meter 3-wood. It's not as good as the other two but much cheaper which would leave you even more credits for wedges.
Buy a 64° wedge then a 60° and a 56°. You could buy one or more of the wedges before the 3-wood.
For irons, you're close enough to L59 to wait for the L59 Pings with high trajectory. I played the Starter irons until I got those.
