After looking around for a bit I *think* that this option basically stops your phone using 2G/3G or variants, and will just become a normal phone.
So basically you can make calls, texts, etc. but you can't use any "data" features. There is a widget you can add called "Mobile" which you can toggle on/off. Just realised I've been using this all along.
I would still like to know if Auto-Sync overides the manually set app updates or if it simply means that the app updates will update on their set timescale.
