Your driver and irons are good enough to use for quite a while(3-Wood is okay, too). Your set of irons has a long enough 3-iron that you can sell your hybrid and add a 64° wedge. That will help your short game greatly. You're close enough to L52 that you could wait for the MAX Spin 64° wedge which is very good and fairly inexpensive or you could get the L39 TaylorMade 64° wedge which is even cheaper but not as good. The L31 64° Vokey is another option if you want to spend the credits for it.
Don't forget that you can select different types of shots to adjust club distance-- Full, Punch, Flop, Pitch, Chip. You can add topspin or backspin which will also affect shot distance. All that will give you more versatility with your 75 yard wedge if you don't want to add a 64° wedge.
I pretty much only use Full, Punch, and Pitch (with varying spin), but that's just how I play. I'm sure other people use a wider range of shots.
