I don't know what progress you've made or if you're still checking this thread after all this time...but for what it's worth. I've been acting and directing since 1976, mostly amateur, some here and there I've been paid for. In my experience "method" acting frequently gets in the way; especially for people who mostly have an understanding of it from pop culture. Far more effective in my opinion is Meisner..i.e. behaving truthfully under imaginary circumstances. It's much more frightening to do but ultimately much easier; it really cuts through the artificial layers of B.S. people frequently try to hide behind when doing "method." I think the best actors are actually doing this anyway to one extent or another no matter what technique they think they are employing. As far as coming to an audition "in character" and staying in character---as a theater director I would find that frankly ridiculous and probably a little disturbing. You would have to be damn fantastic to get cast and even then I would have reservations about what you would be like to work with. Just me as a local community theater director talking, maybe those higher on the food chain would have different thoughts.
