Probably at least another 4 hour training session and lots and lots of editing. Not to be a smarta$$ but that's what it takes.
When i switched from Avid to FCP I hired a trainer for a one on one all day session. He was also available for a long time after that by phone and email for questions.
It was worth every penny. I'm assuming you know how to edit. You need to train your brain and your fingers on the way the Edius thinks, and untrain it on how Avid thinks. The more you do it the easier it will get, so do as much editing as soon as you can.
