Coming to my first question, how do I backup the stock image on my current tab so that I can flash it using odin in case of a warranty claim?
You actually don't need to backup. If you can post the following information, then we can find your stock rom on Samsung update server.
Look in the following files and post what is there:
system\csc\customer.xml only one line: <SalesCode>?</SalesCode>
and from Settings > About device:
HTC One X (Stock Android 4.0.4)
Samsung Galaxy Nexus (Stock Android 4.2)
LG Nexus 4 (Stock Android 4.2)
Asus Nexus 7 (Stock Android 4.2)
Samsung Galaxy Tab 7.7 3G (Stock Android 4.0.4)
Samsung Galaxy Tab 8.9 3G (Android 4.1.2 AOSP ROM)
