This is incorrect and way too high. It depends on how active each
connection is. On the HP PSA (Print Server Appliance) I believe it's
a much smaller number (I'm sure Jerry can give more accurate figures). 
Of course that's for printing only. Depends what the users are doing.

Utter rubbish.

Dependent on your server hardware. Try it until the server melts :-).

No.

No.

Test Samba on your current hardware and find the limits yourself. It
is very much dependent on your organizational usage.
