Thesis planning

I'm a grad student (MA) moving into thesis phase. I'm in the process of creating my "work plan" which is, in my department, a mandatory section of the research proposal. I decided to make mine and reduce it to their's.

I was wondering :

1. How granular I should make my work plan
2. How, using project planning software (OmniPlanner, like MS Project) I can most logically create cycles of revision and modification without making infinite recursive loops. Here I'm not looking for technical support on the application itself, but the logical work flow (like: give yourself two revision cycles, give yourself one but long, etc)

I'm still near the beginning of The Scriptures, but at least I have the five stages generally described and the whole simple-next-action idea down.

Many thanks !
