Hi Steve and Hayley,
Congratulations on your 'scope I've only recently got one exactly like yours, and i'm having an awesome time with it
Regarding collimation, here is a link to an article that really helped me:

Another thing you might want to think about if you don't have one already is to buy some kind of collimation tool, they make the job 100% easier. I ended up getting an orion collimating tool from bintel, and it has been great. I bought it after advice from others on this forum, and the following link leads to that thread. It also contains lots of great general information and other links to collimation in general:

apologies if you already have this info, and I hope you have as much fun with your telescope as I'm having with mine
Kind regards
