1. I am unsure as far as T&C are concerned. There was a lady here that went by the ID SusieQQQ or something like that which file a N-600 on behalf of her child. She might know something about this.
2. I would say Online is faster than Paper. However I don't have any data point to prove this
3. I never applied for Certificate of Citizenship, so I wouldn't know. Again, SusieQQQ would be the go-to-person for these questions.
4. I seriously doubt having a US Passport speeds up any process. As a matter of a fact, USCIS now wants to be the "Dear Department of State, you erroneously interpreted, so please revoke this Passport blah blah blah" organization recently (They don't have the authority to revoke passport BTW), so I wouldn't think it is going to make it any faster.
Prior to 2010, US Passport was considered conclusive proof of US Citizenship to all organizations. Now, US Passport is Prima Facie to USCIS, so USCIS still can refuse to issue a Passport, in which, you would have to go through appeal and have the two department muscle it out. I have never seen Department of State reversing its decision just because USCIS told them to do so.
Anyways, sorry that I couldn't be much of any help and good luck to you and your child's journey to Certificate of Citizenship. I don't think the Certificate of Citizenship is mandatory if your child has an US Passport BTW.
