9/26 is the most recent build, 9/25b2 before that....
Get ROM Toolbox from the market and you can download the most current build from the ROM Manager option in ROM Toolbox. Then use either Clockwork Recovery directly, or use the Install ROM from SD card option in ROM Manager to install. Don't use ROM Toolbox to install, not compatible w/Clockwork Recovery at this point.
You might want to go w/9/25b2 build for now, as some of us have had battery life issues on 9/26, but some haven't, so hard to say how it might go for you.
I was just using this link from the OP, [DEV_THREAD]Droid 2 CM7 with Gingerbread Kernel
which shows a 9-19 build as the latest? I have ROM manager but generally just install manually.
