Tips for retired show collie obedience?

Hi All,
I just brought home my first collie. I've always had retrievers and terriers. She's a lovely retired show girl, but she doesn't have much formal obedience.. i would like to start out on the right paw with her, but know her show background makes things a little different from a new puppy. I have had a couple of guide dogs and trained a few wonderful pups over the years, but would like another set of eyes. Would it be worth having a session with a trainer to get myself started? Otherwise, what puppy training advice do I follow, and how does her life experience change things?
