Congrats! That kit will be fine (for now). I think the write-up also mentioned that there are no bottles...now is the time to ask your friends to save their longnecks or whatever other beer they drink...remember no twist off cap bottles (they don't work).
There will ALWAYS be something else to buy....your choice of products though. If I were to recommend any item it would be an auto-syphon.
The book is great for the beginner. Read it! Highlight it!
Vol 3 is better than the previous ones.
Depending on how enthused you are about your new hobby, there will ALWAYS be SOMETHING you'll want.
I also recommend going through a bunch of the posts on this site for questions (like you'll have) that have already been asked and answered. (Some people have been known to attack newbies for their simple inquiries (present company included) when the answers are already here).
We are not really mean, just a bit aggravated at the questioners lack of research on their own part, as well as aggravated that as much as we want to help, we know how loooong it will take to re-type a good solid reply to you (and others). Hint. Hint!!
We do enjoy most of our time here helping you guys...and yes, there will be debates, sometimes heated, most at about 155F (because we don't want too many tannins in the conversation...if it comes to a boilover). A bit of "Brew Humor". It's a "time joke"...you'll understand it later.
Read your book and research your question are good tips for you now.
