Are you staying onsite? Makes a big difference as far as park hours, etc.
I wouldn't suggest buying TourGuideMike unless you are prepared to spend a lot of time reading and reading and reading and reading (catch my drift?) in order to glean some helpful information. The Unofficial Guide is probably a better idea!
I have read far more negative reviews of Pizzafari at AK than positive ones. JMHO though... Tusker House and Flametree BBQ are better choices I think...
Get there early! Can't stress this enough. If you're not staying onsite, plan on being at the turnstile at least 30 minutes early (that goes for onsite as well). You are travelling at a somewhat less crowded time of year, but getting a jumpstart is crucial.
Use fastpass! I also know from experience that you CAN use an expired fastpass on the day it was issued. This information is becoming more and more known, so I'm not sure whether Disney may change that policy, but we found it made travelling around the park far less stressful!
Enjoy MK! Mickey's Philharmagic is not to be missed! True Disney at it's very best!
