as for riding. if there is an msf course ( or similar training class for your country) i highly recommend taking it. ( knowing roughly where you are we can point ya in the right direction)
pick up a copy of proficient motorcycling. and read it.
find someone to ride with.
its a carbed bike so let it warm up a bit before heading out
practice low speed turns and emergency stops ( find some cones and an empty parking lot for this)
stick to the neighborhood for a while before adding in some faster roads.
get a good helmet and some armor ( jacket gloves pants boots) and wear them
and pay attention to the other folks on the road. they're all out to get us.
