Spellcasting questions

My opponent successfully cast Grenade on my thief and rolled 14  to cast.  He then made a +3 shooting attack against the Thief. 

We interpret that to mean Wizard rolled a 10 and gets +3 for a total of 13.
The thief rolled a 9 with a fight of +1 for a total of 10.

Q1.  Does terrain and moving, etc apply as a penalty?

Q2.  There is a Thug 1" away and caught in the blast radius.  Does the Wizard use the 13 from the previous attack, or does he roll again?

After a successful cast you roll vs target model +3 shooting using regular shooting from the wizard (movement cover ect.) then you roll vs every model within the 1.5" range individually a +3 shooting attack using the original target as the source but the caster for movement.


Caster moves then cast Grenade successfully at a group of 3 thugs.
Original target(Target 1) has 2 pieces of terrain in the way giving a +2 and is a thug who has +1 fight +1 for the caster having moved for a total of 4 fight vs the +3 shoot.
Target 2 has no cover from Target 1 but has +1 base and +1 for the caster having moved for a total of +2 vs +3 shoot
Target 3 has partial cover from target 1 for +2, +1 base and +1 from the caster moving for a total of +4 vs +3 shoot

All 3 are rolled separately. They are all +3 shoot attacks and do not in any way get modified by the caster's shoot score. The casting roll is completely separate from the shooting rolls and must be successful before any of the shooting rolls can be made.

Fabulous.  All perfectly clear to me now.
Cheers.
