Any way to review my account information on computer instead of iPhone?

I setup a lot of iPhones at work for our clients. For every phone I setup, I create the Apple ID and install a bunch of apps we use on site. Every time I go to install the first app I have to punch in the password, then get a popup "This Apple ID has not yet been used in the iTunes Store" and have to go through and fill out the location information, then enter the password again before I can start installing apps. Our default passwords are long, so typing them in multiple times is annoying, and our address information is also difficult to type on the phone keyboard. I'm hoping there's some way I can do more of this process on a computer instead of the phone itself. I tried signing into the Apple ID on the website and filling in the "Shipping Address" there but the phone still asked me to review and I had to fill it all out again.
