There are also other choices for Java IDEs. You’ve obviously found Eclipse, but you also may want to check out IntelliJ and NetBeans. IntelliJ is not free, but has a 30 day evaluation period and a Visual Studio key map 🙂
Shop around, find one that you like and start to use it heavily. They are all very good IDEs, and I’m sure once you use one for a while you’ll get comfortable with it.
