As per the previous post, the G20's should get you all the way to level 79 where you can get the bladez (and boy will you see a difference), and these will get you through to the R11's.
With your clubs, first thing i would do is drop the hybrid and get another wedge. Most top players carry 3 wedges and no hybrid (and when you get to the bladez you wont need it anyway)
Change out your wedges once you get to the Cleveland's (i think you only like 4 levels away so should take to long)
Also learn to play to your strengths, like say you cant make it to a par 5 in two, dont automatically pull out the 3 wood and smash it as far as you can, try leave it so you will have a full wedge in rather then an odd 37 yard shot.
And finally, here is my yardage chart for the G20's,
I did this by going to BPB 12th, and hit 100 shots with each club
(well more, but only recorded the dinged shots) 50 no spin, 50 full
spin, and took the average. The yardage is the final resting place, not
the bounce (which i wish i recorded)
Note this was done with a level 70 Nike ball

5 Iron 190y 194 176
6 Iron 175y 179 162
7 Iron 160y 164 149
8 Iron 145y 148 138
9 Iron 130y 130 123
PW 115y 115 105
Like i said, this is just the average, there were lots of WTF moments
when doing this when shots would fly 10-12 yards longer or shorter, but
these were not included in the final calculation.
Hope this helps.... stay with it, like i have said, once you get to level 79 the game will become alot more fun
