well....
the front brake, practice will be needed, but basicly. You apply the front brake with your fingers, and squeeze the throttle with your thumb and palm wrapped around it. sounds odd, but its quite easy when doing it. practice is your garage...
your bike will proabably be doing as bit more revs than 2200rpm. more like 4-5000 i think. but yeah, its a smaller engine revs will be higher, it wont hurt it.
top gear at 80 will be fine, probably even top gear at 60 on the little 2fiddy.
you can use you front brake while turning, but only a little. generally you do all your braking before the corner, if you only want to wash a little speed off then use you rear. too much rear brake and the rear can slide.
80% of your braking will be done with the front. you will find the rear brake hardly works.
