Rick,
You have a few options up that way, but not a lot. Depending on how far North you choose to stay. If you're going to the tip, that'd be Copper Harbor. The Pines rents small cabins for $80-$100 a night. Limited dining and night life options up there though. Houghton will have more options for both.
M-26 along the Lake is a nice ride, and Brockway Mountian is what every goes up there for. Road kind of sucks on the bike, not horrible, but not great.
I haven't spent a lot of time riding the West end, but some. You can run to Ontonagon and ride the Norwich Rd over towards Ewen and back, I believe this is called the bluffs. Highway 16 in Kenton South to US2 is also a nice ride with some newer black top. Will take you West of Iron River. Another stop might be "Lake of the Clouds" in the Porcupine Mountains. You can google this and you'll see some awesome views, especially in the fall.
I would highly recommend riding up H58 East of Munising to Grand Marais one day. Probably the best riding you'll find in the area. That's about a 200 mile trip from Houghton, or a hundred from Marquette. Le t me know if you have any questions.
