Your driving accuracy needs to improve - it may well be near the root of any issues! As said above get a new driver as soon as you can that R9 meter speed (if one I am thinking of as could not see a L62 one in pro shop which you have I think). Only you know if you can ding often enough! I found the L69 a great little driver - great distance and full of forgiveness. The HL G20 was just worth it over it bit a great driver.
Wedges as above or (if you want something that will last to and in to Legend the HL Cleves - 100, 80 and 60 yards would be ideal with the L79 Bladez. Learn these wedges and remember the punch shot options to. I understand though (before my time) that the Satin wedges you have have are very good anyway. You may well be fine with just one of those level 40 something Pings to compliment what you have. Those Pings are super value and plenty good through to TM even Legend.....
Iron's - The L79 Bladez are the second best scoring set on here, IF you are OK with the meter. If not either of the top two G20 sets are high trajectory great sets.......The HL version is fine for Legend also.................
Hybrid - as above get rid of it asap and learn those wedges. A 3 wood will punch etc - the hybrid is a waste of oxygen for this game much above hack at best!
With all the above done your distance to the pin should come way down...........
