Prudent advice by all and I see the OP did go for the 3 wedges and upgraded the irons. Personally the upgrade to G25's would have been better, but I know it is hard to wait when you are itching to upgrade.
What I will add is try to play all the courses as each is different and you will learn course management and learn to play different types of shots as different shots on different courses work better than others.
Above all, have fun, scores are not as important as having fun playing this game.
Also play multiplayer games and learn and see how others play, particularly higher tiers - most players are willing to share some knowledge.
One point for TM bordering on legend - a good way to get used to longer approaches is ditch the driver and only use a 3W from the tee. This will help you with the longer approaches when you reach legend tier.
