All 110 seats in the Michigan House of Representatives will be up for election in November. Republicans currently hold a 63-47 majority, following a 67-43 democrat majority before 2010. There are "only" 22 open seats following many members being term-limited, defeated, or seeking other office in 2010.
Republicans will gain several seats due to redistricting, though not as many as they could have. Republican Michigander has written a good profile of the races along with presidential election data, racial breakdowns, and brief commentary. The Secretary of State website has a complete list of candidates, along with links to some, but not all candidate websites.
Republican Michigander tends to be more pessimistic than I am in ratings (not just for these districts, but in general), so I am providing my own ratings. I am confident about the districts in my area (Kalamazoo) but many of the others are educated guesses.
The following lists district number, current incumbent, political rating, and geographic description.

Most races will not be competitive, but a few deserve attention.
White and black incumbent democrats Tim Bledsoe and Alberta Tinsley Talabi will battle for this black-majority seat.
Eleven democrats are running.
Former democrat rep. Sarah Roberts is seeking a comeback here.
Former Macomb county commissioner Carey Torrice is seeking the democrat nomination against Republican Anthony Forlini.
Jon Switalski and Lesia Liss are two democrat incumbents fighting for the same district.
Democrat Lisa Brown is running for Oakland County Clerk rather than seek reelection in this now more Republican district. A prime pick-up opportunity.
Staunch conservative Deb Debacker is one of three Republicans seeking this seat.
Republican Joe Graves is running for reelection after winning the seat of recalled Republican Paul Scott.
Republican Rick Olsen retired rather than run in this now solidly democrat district.
Republican Nancy Jenkins is running for reelection after democrats failed to get a recall on the ballot. Her opponents are former state senator Jim Berryman, and 2010 opponent Harvey Schmidt.
Democrat Kate Segal got a more democrat district, but faces a strong challenger in former Battle Creek Mayor Mark Behnke.
Republican Jeff Osterle came close to winning this district in 2010, and it is slightly more Republican now.
Republican Rick Outman will defend against democrat former rep. Mike Huckleberry, who he defeated in 2010.
Party-switching rep. Roy Schmidt is running for reelection as a Republican. For now, he is unopposed, but democrats are expected to run a write-in candidate against him in this swing district.
Republican Kurt Damrow has had ethics issues. He faces a rematch with former rep. Terry Brown, whom he narrowly beat in 2010, if both of them win their primaries.
Staunch conservative Tom Leonard is one of four Republicans vying to replace term-limited rep. Paul Opsommer.
Tea Party leader and Grand Traverse county commissioner Jason Gillman is running in the primary against Republican rep. Wayne Schmidt.
