Personally I would recommend you wait for the Level 59 G25 but will also give you time to earn more credits.
The G25's are the first high trajectory clubs and can take you all the way to legend. Anything less will require another upgrade earlier.
The downside is you will also need three decent wedges (sell back the hybrid) that fit in evenly between your PW.
And of course you will probably then want to upgrade balls - the real money spinner of WGT. But even a cheapish ball like the Tour SD will improve your scoring.
Be patient, just enjoy the game until you can afford your desired clubs - anything less will leave you dissatisfied and out of pocket.
Club upgrade or not, just set yourself personal goals with the focus on having fun.
