Help--Teacher P & 8

I have two questions regarding the N-400 form.

1. Part 6: Information about your residence and employment.
In the past 5 years I went to college for 4 years and worked 7 months as part-time near home with parents and I'll go to graduate school this fall in another state, also I'll apply for my citizenship at the end of the year. How can I fill out the residence in the past 5 years? My home address is still with my parents even I go to graduate school in another state.

2. When I apply for my N-400, I'll be in another state for my graduate school. I still write my home address as my parents'. Can I do the FP in the state of graduate school or I have to go back home to do the FP?

Thanks a lot.
