Does the IS really make that big of a difference with sports photograpy?
If you are only going to be shooting things where you need a high shutter speed to freeze action, then the IS will NOT help. It will help in low light, low shutter speed situations, but these are typically NOT sporting events. I have the 70-200f2.8L IS and when shooting sports I keep the IS off as it is not needed and only uses more battery life. If you will need your lens for other things where low light may be a factor, then get IS, but if only using for sports, save yourself a few bucks.
As to the monopod, yes you can shoot the 70-200 without one, but over the course of a 2-3 hour football game, you will be VERY HAPPY that you put your rig on one as the 70-200 plus the camera, plus a possible battery pack, plus a possible flash will get very heavy after awhile and you will be happy to have your monopod to support that weight. Plus if you get the right releases on it, you can adjust height very quickly if you want to get lower or higher. I use a Manfrotto 679B for my 40D/70-200 and it was ~$70 and is just fine.
As to battery pack, go for it. It adds a nice feel to the camera, makes you and your camera look more professional and has the advantage of a second shutter and * button for focus when shooting vertical. Also, if you are shooting multiple games, it will seem like forever before you need to recharge the two batteries.
