US Immigration from Tunisia

hi everyone, i have a few questions on my mind before i send in my ROC application in 2 weeks:

1- when i send my ROC application how do i know which service centre will have my case ? (i'm based in WA state)

2-should i explain why we don't have joint health insurance and joint phone plan ?

for proof of joint car ownership, should i include a copy of the title of the car of the just the registration or both ?

3- my wife (usc) haven't been working since last summer because she was in school and then decided that she should stay at home to prepare our daughter (my step daughter) to go to school this upcoming September, should i explain that as well ?

4-can any one please provide me with the perfect sample of a cover letter ? i've seen alot but idk which one is best.

i think this is it for now, but i'm sure i'll come up with more question as i go through my application. thank you so much
