How Infused Items obtains, and how they works?

Today found another unclear point for me, please help

I have:

1) Priest-technomancer (level 3), who knows power of Holy Word (Truth, second tier, 25pts)

2) dwarf weaponsmith (level 3) who has Craftsmenship 1, Weapon Forges 2, Dwarven Firearms (pistol 5pts, musket 10pts) and Advance Ranged Weapon (firearms) 1

I would like to teach my elite warriors to use Advance Muskets, and infuse this muskets with Holy Word by my priest techomancer. As I understand level 2 warriors has limit Property 2, Weapon Forge with Craftsmenship 1 increase this limit to 3, I join Technomancy priest to level 2 warriors squad and can pay 18pts per musket for every model in squad who use this weapon. Is it correct?

And when this model will fire with muskets i will roll for hit using Combat Situation (with bonuses from musket strength or ranged bonus) and Ranged stat, and if result is more then 7 and less then 13 (power difficult 8 mortal threshold for humanoids 12) i can instead of resolve hit with muskets use Holy Word on target. Is it correct?
