OK, been quite a few posts out there, within the CF community, about how you can download the ColdFusion RDS plugins for Eclipse (Well, CFEclipse). Now, if you have Flex Builder 2.0 then you already have it. At least I think you do, it might be an option during install, but either way it's available to you with Flex Builder 2.0. But, you can also go to that first link in this post to download it by itself. Install is pretty cut and dry, but you kind of have to search a little to find out what to do next.
