how to start with blackberry development

I want to start with BlackBerry development for smarthphones.

I see two ways...

1. Eclipse
2. Visual Studio

I have Windows 7 64 bits... with Visual Studio 2008. I install the Visual Studio Plugin, I create a BlackBerry Project, but when I try to Save the Project I can't, a message error appears. Other problem are I cant compile to the simulator. I have the simulator for BlackBerry Curve 8520.

How I can develop with Eclipse... I see is other method... but How I can link the simulator with eclipse...

If Is eclipse... what language is needed ??... In Visual Studio are HTML + Javascript... But... with eclipse ?? is HTML + Javascript开发者_开发百科 too ??? or maybe are JAVA ?

I hope anybody can help me.

Thanks.
