Multiple iPads...set up as new iPad or backup?

I have a personal iPad which I have Mixpad on and have since bought another for our sound engineer. When setting up in iTunes I notice that I could do a backup or setup as a new iPad. I would like to set up as new iPad with only Mixpad and a few other apps that doesn’t have all of my personal information on it. If I set up as a new iPad and I purchased Mixpad on iTunes will I still be able to select what apps I have already purchased and place them on the iPad without repurchasing them? It seems like it’s a no brainer since it’s registered to my account but I didn’t want to reach a point of no return and then have to purchase again…guess I cold feet. Thanks!
