I've been using this method this week and thought I'd share this excellent tutorial on a ProRes workflow in Premiere Pro.

I'm actually pulling HDV right off cards with no transcode, dumping them on a ProRes timeline, no rendering - then exporting as ProRes at the end.
On the export side I'm having to do lots of individual cuts for this job, and this is a bit of a pain because I can't figure out a useful batch method without making each cut its own sequence and using AME, but the time saved at the start mitigates this for me right now. Hopefully some kind of batching will be forthcoming.
