Here's my 5 cents..
You are at a high enough level to be able to get the Burners which is what I would do in your position, I went the G20 route at L50 odd and then the L83 G20's and now have the R11's..
The burners are the "2nd best" iron set on this site behind the R11's, so you would be able to get used to the slightly faster meter speed, the burner 3 and 4i will stop better on the greens due to their high trajectory..
I would bin the hybrid and get 3 decent wedges, I have the tour w pings 60/85/105 yarders which covers just about everything from 7 yds to 108 yds and the spin is easy to control..
I would recommend any other putter than what you have now, be it the cheap spider, the Daytona or Ghost manta, I know there are some VERY good players who still use the starter putter but I would advise a new one..
Last but not least, play with decent balls to get the best out of the clubs mentioned above, if credits are a problem, the WGT Tour SD's at 90 credits a sleeve are the closest you will get to Callie/Nike performance..
Good luck :-)
