Check out the self-proclaimed "QlikView Answer-man", Bill Karp, ex-QlikTech consultant's youtube channel.
I've watched most of his videos. He's really good. I've learned a ton of shortcuts and have a better grasp on a lot of concepts used in reporting.
His first few videos cover more of the development side, and torwards the end he covers design.

He's been posting more recently, so there may be more to come as well.
