When you start the Mini, can you get beyond the screen that wants you to attach to iTunes or a network? If you can get to the home desktop, the screen that just shows the included apps, tap Settings, then highlight General if it is not already in highlighted, then About and at the top will be Name > there you want to give your Mini a name, such as kgomos iPad Mini, or what ever you want to name it 🙂
You can manually enter email account info but that would be a lot better to do with a network connection as the Mini can download the info it needs for preloaded providers such as gmail, or AOL,
If you do not have internet access at home, do you have an iCloud account seetup? I am assuming you have an Apple ID since you are on here asking questions. If so, while it isn't secure, can you go somewhere that you can access a wireless network, such as a coffee shop or a library? You can do al of the setup things much more easily that way.
Do you have the User Guide that should have come with the Mini? That and the PDF file I linked to above will offer a great deal of help.
