There's a great thing that a theater company in New York City is running called Audition Bootcamp or something. Apparently they are having all sorts of sessions with professionals (like casting directors, working actors, directors, agents, etc) in the business, some seminars, and even one on one time with people who can give you tips and advice on the pieces you've chosen and what place might be best for you.
I think those types of things are essential, and priceless. Like Mastercard. :-)
They give some pretty detailed information on their website:

Good luck with it all!
