Congratulations on your upcoming move! Good luck on your visa application. I just have a few tips for you.
Once you get all of your loans in order, make sure that the school sends you a certified copy of your fees, loans, etc. The school I went to over-nighted this paper to me with an official stamp on it. Include this paper in your application (and make a copy so that you get your original back). Make sure that you print out your CAS form, as well, as you will need this in the application. Carry both the loans form and your CAS with you when you enter the UK on your student visa. The IO asked me for both when I entered the first time. I always had them with me when I traveled but was only asked for them the first time when I said that I was coming to begin my university course.
Best of luck! I am sure that you will have an amazing time!
