Congratulations Nathan and commiserations to your bank account. It is a thrill to look at your first astro images coming in from the camera so my suggestions are work on the polar alignment and as JJJ said try to avoid camera shake. I bought a timer from ebay that allows me to multiple shots at different exposure times. Set and walk away. You can see them here

Also when you have alignment better you can try for longer exposure but will definately need a guiding system for long exposures. But that can be down the track.
