Oh, my, you probably should have practiced on some scrap sandwiches before starting on a 'real' quilt. It's an acquired skill. As far as 'how much free motion' it's like any quilting question: read your batting package. That will tell you how far apart your quilting can be and still secure the layers. As far as the binding is concerned, most people will bind after. sometimes quilting will distort the quilt and you may need to square it up a bit.
I'm sure that it will be lovely. Post a picture when you're done.
