please forgive me for so much crap here... :p hehe

close. just don't play the first E note... what I mean is, just play the 7th fret 3rd string, bend it upwards to make it sound like the 9th fret... that is a full bend, if you bend it up only enough to make it sound like the 8th fret, then that is a 1/2 bend, a 1 1/2 bend would be making it sound like the 10th...
so if you were reading tabs then:

G|----7b(9)-----
or
G|----7b9-------
would both describe that particular bend that I described

what you described was basically:
G|----9p7--7b9---
but that's just one example, you can bend any fret of any string.
and if you should happen to see something like this
D|----4b5b4---
then it means that you bend the 4th fret of the 4th string to make it sound like the 5th fret, then bring the string back down so that it is back in place and sounds like the 4th fret again
