Congratulations, Jason!! I'll be looking forward to more examples and some outside photos, as well. I'd give the manual a good read through and take a look at this thread in the Photography Techniques forum called Learning How to Expose Properly: the basics. This is a really handy thread with excellent information and how to advice. Once you start down that road, I think you'll find that between you and that NEX, you'll really start cooking!
Welcome to the NEX fold Jason like you I bought the 18-55mm lens withe camera; hopefully I would like to add a true macro lens which I understand may not be too long in being released!
I have no other lenses from any other cam: so will stick with the Nex range. I haven't used the auto; mainly using the AV; just experiment with your new camera and enjoy.
