More Photo Shoots!!!! And a Question.

I have not just one photo shoot to do, but 5!!!! I am so excited!! This is exactly what I have been wanting for years! Now I am finally getting the chance to do the thing I love the most... and get paid for it!!
So, does anyone have thoughts on copyrights? Should I start this now, or wait until I'm a little more known? If I do copyright my photos, what should I charge for getting them printed?

I just did my first paid photo gig last night! This is the first step for me to becoming a professional photographer, which is exactly what I want! Here are a few samples from the shoot (these photos are copyrighted, please do not make any copies):
