There is (well there was last year) very few learning resources for OpenGLES 2.0
but i did find a book called OpenGL ES 2.0 Programming Guide by Aaftab Munshi, Dan Ginsburg and Dave Shreiner.
i remember i learnt a little bit of it, but i couldn't retain the knowledge due to projects just being cancelled.
I would pass on my knowledge of opengles 1 and 2 to you but i'd have to find it in my brain first.
going straight to 2.0 is probably a good idea.
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Objective C, C#, Java, MEL. Python, C++, XML, JavaScript, XSLT, HTML, SQL, CSS, FXScript, Clips, SOAR, ActionScript, OpenGL, DirectX
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
