The remainder of the content in Beginning Arduino Programming has some nuggets of useful information in it. However, it starts to have a lot of other content that's either not relevant for the equipment we have, or is at a broad descriptive level that's nice to read about but isn't so useful. Skim the rest of the book quickly so you're aware of what's there, and focus on anything that interests you. You don't need to post any questions to Campuswire if you don't wish to, but you can if you like.
