I can't help you with 1 and 3, but for 2:http://www.rapidtables.com/electric/Solder_Bridge.htm
That item is not "Ferrite Bead", is SMD Poly Fuse.http://en.wikipedia.org/wiki/Resettable_fusehttp://parts.digikey.com/1/parts-kws/smd-poly-fuse
A ferrite bead is a good idea but not absolutely necessary. A fuse is also optional but will protect your computer's USB port. I think this is just a design decision that the designer made.
The FTDI specs recommend the ferrite bead, but none of the Arduinos has ever included it.The part labeled F1 in the schematic is indeed a fuse (self-resetting polyfuse.)........
