F2A category.Applying for citizenship.

[zalak1973]

I am green card holder and I filed petition I-130 for my spouse , wife (beneficiary) and child (beneficiary derivative). Now I am eligible for citizenship and will be applying for naturalization shortly.
Now question:
1. Will I have to re-apply for our (me and my spouse, wife) child (son) after I get my naturalization certificate or USA passport.
2. If I have to file a new petition for my child, then what would the process and which form I have to fill.
3. Do I have to update the status of the petition for my spouse and child for category change so that their file gets processed faster?
4. Will my wife and son (after filing new petition) will get same interview date? Not sure how it works at all.

I will appreciate for the reply.
Thanks in advance.
