Rafael,
I'm not sure why you're seeing an issue running a 32-bit build of Eclipse on a 64-bit platform since the OS should be fully backward compatible. I believe you simply have to run in 32-bit mode and that should resolve the dll issue you're seeing.
As for Easy Eclipse versus MyEclipse, MyEclipse is a fully integrated IDE designed to facilitate
Java EE and AJAX development. It isn't a collection of independently built plugins like Easy Eclipse but more like IBM's Rational tools, Borland's IDEs, WebLogic Workshop, in both the level of the tools provided as well as their integration. The main issue with plugin collections is simply that the individual pieces are not designed to work together since they were developed independently by different sources. This is most evident at the "seams" as you cross from the functionality provided by one plugin to another. That said, plugin collections might be "enough" for certain types of development. To see what MyEclipse has to offer, I'd encourage you to look at MyEclipse in action as Riyad posted
