That's interesting. I love to talk with you sometime about your experience with those higher priced jobs. I'm particularly curious about what kinds of clients are mosting higher price jobs on elance, since our experience has been that it's mostly a race to the bottom. Could you send me an email: andrew at getlambda dotcom

For the types of projects we work with, "exceptional developers" might be better described as "competent developers, great entrepreneurs". Of course, that wouldn't be ideal marketing copy :)

In general, raw technical ability isn't a huge factor in commanding higher rates. There's definitely a minimum threshold someone needs to pass, but you'd probably clear that easily if you've been freelancing for 5+ years.

Instead of learning to code faster, you'd be better served by learning to code less. Clients often have big ideas that would take 6+ months to build in their entirety, but which could be shipped in weeks by eliminating unnecessary features. Convincing them to cut those features is a skill in of itself, which is often what separates "freelancers" from "consultants".
