#1. At incorporation, you will have decided much of this--or if you are like most people, you would have accepted a standard set of corporate documents. I assume you have a C Corp or an LLC and depending upon the state, these documents will prescribe different ways of nomination. Either read the documents or have your attorney summarize the procedure for you.
#2. If your situation is like most, you will have to nominate each person separately and present them to all shareholders in written form with approx a 200-word summary of their experience. You will, in most cases, also have the ability to present an entire board to the shareholders, but they will still generally have to vote for the individuals.
All the best,
