I'd say an hour commute isn't TOO bad, but you'd have to ensure this doesn't demotivate you from attending lectures a few months into uni after the ''newness'' has expired. You could probably try looking for a 1-bed flat close by, they would be solo-living, and you wouldn't need to share. If you decide to share, it's not too bad, and you get used to living with others quite quickly. Bonus if you can get along with flatmates as they can become friends for life and your experience at uni would definitely improve. I lived in halls, so I can't give you any further opinions on private renting/sharing a flat.
Go to the student finance website and start the application process; you will quickly find out how much you are eligible for. Assuming you get maximum mantaince loan, you could potentially get around £9-9.4K; this would have to be budgeted to account for rent, food and living expense - a lot of students do get a part-time job, and your university should frequently have job opportunities listed. Of course, take the initiative and find a part-time job yourself asap. Saving money would be very wise and will help you out, especially in the beginning as you settle in. Student loans are paid in 3 instalments, I believe, so if you don't get a job, you need to make sure you have money between instalments. I recommend opening a student bank account because many of them give you an interest-free overdraft that comes in handy for some.
