You asked for advice from the 'experts' so I don't think that I quite fit the bill. ;) But, I have been around awhile and have managed to claw my way up to the Tour Master tier so I'll give your question some feedback. Mind you, this is what I'd do if I found myself at your current level & tier and knowing what I know now having been there.
I have looked at your current equipment and this is what I would do. I'm throwing these out assuming that credits are no issue.
1. L48 Rapture Irons. Good distance, slow meter, good all around clubs. I used these for quite some time and really liked them.
2. Upgrade your putter. I'd wait til you reach L55 and get the Daytona. I still use it to this day and continue to improve with it. I also used the Spider but in retrospect I can't give it my recommendation. I haven't used any of the GhostSpider Putters but you might try renting the L35(?) and see how it works for you.
3. Wedges. There are several that are unlocked for you know that will give you better performance than those you have now. Ultimately, the top Level Cleveland's would be my advice. But any upgrade you can get at this point will definately improve your short game and knock some shots off your rounds.
Most importantly, everyone finds different things work best for them. These are my choices based on my game and my experience. The next guy or gal might completely disagree with my choices. One of the nice options here at WGT is the ability to rent clubs and give them a try before going all out to buy them. Weigh all the advice you get, try out some rentals, and ultimately make the best choices for you and your game.
Best of luck to you! Most of all, enjoy yourself!
