One working FCS will suffice for any number of MT missiles and/or SML;
the
same FCS may be used for direct-fire (eg beam) weapons as well.

Yes

Yes, depending on your house rules.  I'd allow missile fire into A arc;
the
rules-as-written don't permit it unless you use the optional
you-can-shoot-into-the-aft-arc-if-you-don't-thrust rule.
