In addition to the User Manual and Release Notes (RTFRN), the Axe-Fx II Wiki is the best place for details, tips and tricks and features of the Axe-Fx II. Much of the information is compiled from the Fractal Audio forum, with many contributions from Cliff Chase himself, creator of the Axe-Fx. Forum user Yek created and maintains the Wiki, with help from M@ and SC09.
A very helpful section is Yek’s How To’s available here: http://wiki.fractalaudio.com/index.php?title=Yeks_How_Tos
Another helpful page is this post on the Fractal Audio forum: http://forum.fractalaudio.com/axe-fx-ii-discussion/74884-troubleshooting-faq.html
