Landing with full flaps should be part of your skills, along with landing with no flaps. The C182 lands just fine with 40 flaps and a full stall. Many more nose prangs come from "flying it on" (no flare) and reduced flaps than full flaps and full stalls. If you do happen to bounce, go around. The third impact is usually where either the nose or the tail strikes.
Load a third person on board and try to get as near to max gross weight as possible. It's a bit different bird at max weight than 40% below gross.
Trim will be your friend, much more so than in the 172s.
Don't let the G1000 scare you. It's a big Garmin 430. Download and play with the simulators. Spend some time on the ground with a competent G1000 CFII and your inflight time will be greatly reduced.
Spend the time to learn engine management. If it's a turbo 182, 5 minutes to cool the turbocharger before shutdown will extend the turbocharger's life. Descent planning and airspeed control are more of a factor now than in the 172s. You can enter the pattern at 140 knots wondering when you'll have time to run the checklists, or, you can run the checklists and slow the plane before the pattern, enter the pattern at 100 knots and enjoy a normal approach.
Forget the old wives tales about 'square', M.P. below/above RPMs, leaning, and so on. Use the numbers in the POH and you won't go wrong.
Fly SAFE!
