All of the above advice is good Adam - especially using a Bahtinov mask (they're not too hard to make yourself) and live view on your laptop using EOS utilities.
I'd also recommend joining the ASV and/or attending an Astro Camp like Snake Valley in March.
All the best, and welcome aboard.

PS here's a link to making a Bahtinov mask for your own scope.
