1)The main documentation for the Full Calendar options is at http://www.fullcalendar.io
indianbendsolutions.net has limited documentation on plugin usage.
2)See Full Calendar timeFormat option. (h: = 12 hour H = 24 hour)
3)There is not a feed legend to be displayed. This could be a future enhancement.

How and where would you want a feed legend to display?
An alternative may be to display the feed name in the qtip bubble as the first line.
I just put a statement at the top explaining. But, yes if it could also show the calendar event as a title I think would be helpful as well. When you look at the calendar you don’t know what colors are what, so a legend helps people know without having to hover.

I just posted version 3.0 of the plugin which adds an option for a feeds legend.
