Well,
After looking at your clubs, your wedges would be the first clubs to upgrade. I would suggest the 2 Ping Master wedges. I can't count the times those master wedges either dug me out of an ugly lie or simply gave me a beautiful approach or surprising eagle.
However, if you're not going to upgrade your driver, I would suggest the TM Master wedges because they give you a little more distance which you'll need if your driver gets you within wedge range.
Your putter will get you by if you're used to it already, but I would promote the Rossa as the best bang for your buck.
Have fun,
TMPC
