If I was looking for elk, I'd try and hunt as far south as I could (watch out for the gamerange, you need a special tag) towards the blackfoot or over towards Ovando. I wouldn't go north of Seely, the farther you get down the Swan valley, the less elk you will find as a general rule.
As far as muleys go, you'll probably find most of them on the Swan range side of the valley, and they could be anywhere along that side. The biggest problem is getting up high.
As somebody else said, you're in good whitetail country, but there are much better places to chase elk and mule deer in Montana than the Seeley area
