That all sounds far more complicated than it actually is. If you get hold of a street plan of Leicester you'll be able to see that the walks are quite short and easy to follow.
You can view a timetable for route 302 by going here:

Enter '302' as the route number. When you're prompted to select a route, choose the first option (Beaumont Leys - Braunstone - City Centre). To expand the timetable to show intermediate stops, click the '+' buttons.
If you're travelling as a student yo might be interested in Arriva's ticket which gives unlimited travel for a 3-month period. For the current period, through to 14th July, this costs �67.50 if bought online:

PS: If you hate walking, just ask your neighbours where they catch a bus into the city centre. Then take service 51 from Haymarket stand H4. These run every 15 minutes. Alight at Rowley Fields Avenue, just before Braunstone Lane.
