Greetings from the road,
Yeah I am currently using Premiere Pro CS4, and still getting used to it, but just completed some freelance work on it and it is starting to iron out. I have been using it since college (5 or so years) and my advice is to just go out and grab some B roll then play around with it in editing (if you have the time) I did that at one point and it really helped because I could focus on playing with controls rather than a deadline or pleasing someone.
As for the camera I have about four shoots under my belt with it now, and still haven't quite gotten the hang of it, I can't seem to get a big offering from the focus, I don't know if my back focus is off or if I am just trying to do something the lens won't do, but almost everytime I shoot a scene I have to reset my back focus to give me the most play.
Anyway, I'm glad you are enjoying it, keep us updated on the work you are doing with it, I'd love to see some footage.
