Hello geordie.
My first thought on reading your post is that you have been miss-sold the product as the product you seem to have wanted is Norton Tablet Security (which is designed to work on tablets without SMS etc.). Norton offer a very good refund policy and in most cases, if you have had the product for less than 60 days they will give you a full refund if you uninstall it. So you might like to think of that option.
To try and answer your questions:
1 - Yes
2 - With the full paid version you can then obtain and install the Norton Anti-Theft plugin which allows you to track your phone, lock it etc over an internet link (assuming you use WiFi to do your internet shopping etc..). It does also have other features on the paid app that should work on your device.
3 - NMS should give you the same protection for online shopping that Norton Tablet Security would give you.
I hope that helps. Feel free to come back.
Good luck.
