Agreed, Paul Neale is great, he puts on classes from time to time, in rigging and scripting. They're great, I've picked up quite a few tips and tricks from the ones I've joined. He's a very approachable guy too likes to help people who are willing to put in the time to learn. Digital tutors has some decent tutorials too.…
Paul Neale has some great rigging tutorials, he teaches both FK and IK Bones rigging and a little bit of scripting for things like shoulder twists and such. Since you seem to already know rigging that intermediate course would suit you.
