Double congratulations.

As far as mics go, I strongly recommend a wired headset mic, because it
1. Keeps the mic close to your mouth so that the harmonies are always right on
2. It gives you the ability to make eye contact with all of the audience all around you.
3. It gives you the ability to sing and look at the buttons you are pressing on the keyboard
4. It's lighter and you don't have to carry a boom to gigs.

I keep my headset mic in my keyboard gig bag, and with my monitors in a bag slung around my shoulder I go to all my gigs with one trip with my keyboard and stand on a luggage cart.
