It looks like you had trouble calculating service size perhaps as well as grounding electrode conductor size, calculating bonding wire size. Most service calculations can be found in article 220.

Bonding and grounding electrode conductor calculations are in article 250. There may be some other avenues that require calculations-- wire size (article 310) etc.
