Since I have gotten no reply with the registration concerns I have - could someone please direct me to a place where I may be able to get some answers?
First, to be completely honest, I mostly skimmed sections of your thread. (Sorry, the wall of text was somewhat intimidating.)
Newegg and Amazon both should've sent you order confirmation emails after they received your orders. If you scour your email inbox, you should find something that will be acceptable as proof-of-purchase.
You'll have to refer to individual company policies as to whether or not product registration is required prior to taking advantage of warranties.
