You aren't going to be able to run Gingerbread yet, the closest thing you can get is to install a custom rom and then place a Gingerbread theme on top of it.
Custom roms come in two flavors, Blur and Blurless.
Blur uses the stock motorola user interface that you are probably used too.
Blurless is basically as close to the stock android operating system that we can get.
I'd suggest browsing through the ROM sub-forums here and finding a rom and a theme that you like and that post that in here. I, or someone else, would be happy to walk you through the steps.
