fontlab opentype features coding

OpenType comprehensive beginner help materials?

Forums: 

I'm pretty new to font making and I've got FontLab Studio 5, but I'm having trouble understanding all the steps I need to go through to make a lot of the OpenType features work. I understand the concept and I get what most of it means, but it's like I'm missing some pieces to the puzzle.
So are there any books or any tutorials you can suggest that cover the basics of OpenType (hopefully addressing FontLab specifically)?
Thanks!!
