Oh yeah. They'll have break out sessions for all skill levels and lots of camaraderie and tom foolery to fill the gaps. What i'd do is join your local homebrew society and get to know them, so you'll have some contacts to pal around with both during and after the crowds at the national homebrew event. There will also be vendors hawking all kinds of wares and it might be a good opportunity for you to pick up books or supplies no matter where your brewing skill is at.
IMHO, i'd get a list of the break out session schedule when they release it online and note the dates and times of the topics that interest me, and just hit those hard.
Beer so good, it's frightening.
