I've been to at least 2 games a year for the last 6 years or so. Being your first time in Lincoln, allow yourself plenty of time to get from Hotel to Stadium / downtown area. Once there, you will want to walk around and take in the atmosphere. Walk around the stadium, check out the Pavillion, and maybe catch the Unity Walk. There isn't really a need to be in your seats more than 30 mins before kickoff, unless you want to watch all the team warmups. Hope this helps you out. There will be so many things for you to see, you'll be in awe, make sure you take the time before the game to take it all in. Congrats on the tickets, and have a great time. btw i'll be at that game as well so if you get lost look for the guy in Red!
