Well - the BEST place to stay is probably the Sheraton which is right on campus and walking distance to the Dome. If you are going to do that though, better make your rezzies now b/c that place sells out quick for big in-conference match-ups.
For tickets I always go through StubHub because I do not like sitting in the upper reaches of the Dome. Again, the big games are a lot of fun to go to but you really do need to plan far in advance.
Good luck, let us know how you do.
