(Answered) (Errata) Artillery and the multiple targets modifier

[Eminog]

There are some units that mount regular weapons with artillery and some that mount two artillery weapons:
-If a mech or vehicle shoots artillery at a hex in the artillery targeting phase, and then attempts to shoot a regular weapon in the weapons phase, does it get +1 for the weapons phase target because it is applying the multiple targets rule (tw 108)? 
-If so, can the unit choose the artillery shot to be the secondary target even though it is shot earlier in the turn?
-If a mech has two artillery weapons and shoots at two different hexes, is the multiple targets rule applied? 

Thank you for taking the time to answer questions.

1. No, because it is a different phase.
2. N/A.
3. Yes.

3 isn't spelled out in the rules, since they generally seem to assume that one unit has one artillery weapon.  But we've had units with multiple artillery weapons for a long time now, so we need to catch up there as RAW is silent on the matter.
