Setting up iPads in education - how to use itunes accounts?

We have 30 iPads to deploy and i m nearly there. I have them all configured using apple configurator and have used the profiles for wifi and lock policies.

My questions is what is the best way to deal with itunes accounts on them? Each iPad will be issued to a individual teacher but i will be purchasing apps using VPP and pushing them.

If i sign in on each iPad using a general itunes account i.e itunes@myschool.com is that any more manageable than letting each teacher create there own itunes account and signing in themselves? Will this prevent me from adding apps when I have them returned to the configurator.

Can i use a general itunes account on more than one ipad.

sorry for the long winded message but any help would be greatly appreciated.

Thanks
