1. It seems that you lived in Minnesota for 8 months so the answer is "yes" but you need to provide evidence. What is the home address you provided to your employer, if it is in Minnesota and your state tax was withheld, no problem then.
2. In general you should do the 2 states separately (8 months and 4 months). I did CA and MD separately when I moved a couple of years ago.
3. If there is special arrangement between the these states (like Maryland and Virgenia) you can file for only one state.
