I'd do multiple lists of topics, so we can gather into each use-case the topics most relevant to them… Quick Start Index for Individual Users of an Existing Account. Quick Start Index for Owners of Medium to Large Sized Businesses. Quick Start Index for Small or Home Businesses.
I'd make the first list in each of those sections the order they are likely to encounter things during a new setup situation. I'd also make a Glossary sort of area that gives one or two sentences each on all the important terminology used throughout our system so they can figure out where to look something up alphabetically
The second section in each of those should be usage (after setup is complete), so nothing involving changing any settings, stuff about dialing, how to find logn distance rates, how to check voicemail online or via phone. how to send and receive faxes. And I'd make more of a FAQ to cover the edge cases — things that are odd questions that aren't part of the normal set up phase.
