No worries
Car parking on campus is extremely limited, there are car parks in Leicester City Center but I don't know how expensive they are (or how busy they get).
parking outside Leicester City Center and using a Park & Ride system should be better.
8 hours per week should only mean 2 days per week, unless your lectures/tutorials etc are scattered all over everywhere, in which case you'll have to ask to see if they can be rescheduled - I successfully managed to get a 4-day week changed to a 3-day week in my final year as there was one day with only 1 session!
Nope, I didn't have trouble with that, I got to know everyone in my class and made friends quite nicely
