The #1 thing I see new managers miss on is delegation. It is not your job to do it all, it is your job to make sure it all gets done. Your team's job is to get [whatever it is you do] done, your job is to make sure they have to tools/resources to do [whatever it is you do]. You now have a dozen smiling faces looking at you, with a dozen different motivations. Don't assume everyone has the same motivation as you, you're going to have to figure theirs out.
Your position has changed, expect your relationship with former co-workers to change. Sometimes good, sometimes bad, but it has changed.
If you see your team as your minions, they will hold you back. If you see yourself as their support/mentor/advocate and make sure they have the resources, proper motivation, and achievable goals, they will carry you up.
