Bob, I disagree with your comment to an extent, but I'll just leave it at that.

Please, feel free to expand on your remark, I thought the whole reason for the apprentice system was for experienced tradesmen to pass on their knowledge to their apprentices. Is that no longer the case?
 
I really don't see why you are even attempting to install this service in the first place. You are obviously too fresh to the field to even attempt this. You should be working under a Certified Journeyman or Master.. My next problem would be that you are using this forum to basically put together an instruction manual for yourself. The code book should have all the answers you need, and if you can't follow what is in the book.. Maybe you should wait until after you finish school...

I feel the same way. Electrical installations should be supervised and experience should be passed from Journeymen to Apprentice..

He just told me to look into , back to back, 400 amp service . He said he thought the wire size would be for hot conductors 4/0: neutral 2/0 and ground #4 he said he wasnt fo sure

you can't downsize that neutral unless you at least meet all these requirements 215.2 220.61 and 230.42 and this appears to NOT be point of service and if that is true then these 2 panels are only good for 180 amps each.

Good point 59 flavor sparky.

A DIY 400 amp service? There is no way an apprentice has been left the responsibility for that kind of installation.

Sorry bro, but there is no way you are going to get the answers you are looking for here.
