They seem to move the visitor section every year, so I am not sure if it will be on the east or west side. It may be on the south-east side, which is behind the visitors bench. They might move it to the south west side, which is behind UNC's bench. Other than the student section, there are some chairback seats near the 50 yard line on the west side. It is a pretty basic stadium, and if they follow what they have done in previous years, once you get in you can sit pretty much wherever you want, except premium sections (ie chairback).
Here is a seating chart:
