Do I need to have wireless Internet access on an iPad every time I use the app?

No, not everytime. 
You will need to be connected to wireless internet for the initial download and setup, and should connect occasionally to sync and back up your page sets, but you can use the app any time without Internet connection.

You should, however, connect periodically (whether backing up data or not) to keep your subscription active.
