Regarding the second part, I think, the information you provided or interpretation of the information is wrong. You can file for N-400 while your I-765 is pending ( as many of us on this forum has done it). But your N-400 cannot be approved while your I-751 is pending. So at the time of your N-400 interview, if you I751 is still pending ( less chances) then in the same interview, they will approved I-751 first and then do naturilization as by rule, you need to have I-751 approved at the time of your Citizenship approval. But again, it will have no impact on filing your N-400 (citizenship application).
The criteria for naturalization states that you have to be permanent resident for an X no. of yrs. (3 in case of marriage, 5 otherwise) to even apply for naturalization.... in the case of an I-751 pending, you are still a conditional resident, not permanent resident. You attain permanent residence upon approval of I-751.
Now i am not desputing anyone's N-400, which they filed and got approved concurrently with an I-751; I just wanted to pass along info which i was adviced by attorney's, who actually do this for a living. Rest is all a matter of luck and one's own judgement.
