I ordered the Home Premium Upgrade from Amazon, but what would like to know is this ... I am currently using build 7260, will I need to do the double install method, or is going from a RC build to the retail considered a true "upgrade"? Any clarification would help!!!

Well some people are saying that upgrading from RC to the real release is possible, while other people are saying its not. We probably won't know for sure until MS says something about it, or until you try it for yourself. I wish I had a definitive answer for you on this one. Maybe someone else can shed some light on any info they gotten. Double install is sure to work, but your question leads me to believe youd rather upgrade from the RC you have right now. There have been some places that lead us to believe it will be possible, but we prolly won't know for sure until either you try it for yourself when you get your disk or MS says something about it.

MS has said something about it in their engineering blog. Engineering Windows 7 : Delivering a quality upgrade experience

In that link, they give a method for doing an upgrade install from a RC to the RTM. I used it to go from 7232 to 7264 (which was more like an RTM in that it didn't use the beta/RC keys) and it worked. But that was ultimate to ultimate. Anything else might not work.
