You will have a great time I am sure, but I would suggest you review a few of the many threads on here regarding Seaside and Yacht club, then come back with questions if anything is still unclear, as all of your questions so far are answered multiple times in those other threads...
We are also new to MSC and will be in YC in June on Divinia, and we've found the threads here and the many review videos on YouTube to be a great help.
