What are the limits of the Deposit of Faith?

The Deposit of Faith is limited to the words and actions of Jesus' historical life--is that correct? Only those things that He taught to his disciples and commanded them to pass on to others can be considered part of the Deposit of Faith--is that correct? There were no additions to the Deposit of Faith after Jesus' ascension--is that correct? After the Ascension, all we can is interpret the Deposit of Faith since public revelation has finished and there is no more revelation to come--is that correct? Those sound like different questions, but it's hard to put the whole question into one sentence! :)
