Does MyEclipse support Groovy on Grails and/or Ruby on Rails?

You'll currently get the best Groovy Grails support from an IDE in IntelliJ IDEA. I've have heard that good things are happening with Eclipse and Netbeans, but IDEA is the current frontrunner.
On another note, it is very hard for an IDE to give you the support your are used to with Java when you're using a dynamic languages. There are just so many possibilities about what you are meaning when you type, the IDE almost has to be running the application to know what you are referencing.
