8th Ed. let's talk about Chaos Dwarfs

I decided to start a Chaos Dwarf army: I wanted a second army, I wanted a chaos-oriented faction because I usually play 2vs2 games and I want trusted alliances, I wanted hard hitting ranged attacks... and CD still have magic, good close combat, a good background, some monsters and in general a lot of interesting stuff.

First problem: I cannot spend tons of money buying forgeworld miniatures, even if they're fantastic, so I think I'm going to buy GW dwarves and paint them with a red-black or violet-black theme, maybe with some minor conversions. I could buy the old models since many players will sell them because of the new book, and I could unpaint the painted ones with dettol. Maybe i could buy the battle skull pass box, so I would have some dwarves and some goblins to make hobgoblins (even if I don't think I'm going to field hobgoblins). I'd like to have some more cheap alternatives tough (I would use them in friendly games, so i cuold use unofficial miniatures)

second problem: since english I'm not a natural english speaker I'm a bit confused about some rules, and I'd like to have some help from people who knows CD

1) if I equip a sorcerer-prophet with a magic weapon can I choose if using the magic weapon or the darkforged weapon or I have to use just one of them?

2) deathshrieker rocket launcher: when using demolition rockets in wich way the hit is resolved? I just don't understand if it works like a strenght 8 cannon who (hopefully) kills just the first model it hits and never scatters (I hope it works this way) or if I have to scatter once and resolving the attack on the model I hitted (if I hitted something).

3) can the bull centaur taur'ruk take the "CD only" magic items? It could be a stupid question but since bull centaurs are chaos-modified dwarves I don't understand it

4) breath of hatred: since hatred works in the first close combat round should i cast this spell on the first close combat turn or i can cast it in other turns and give hatred to my units even if it isn't the first close combat turn?

5) is there a single reason to take a chalice of blood and darkness?


Now i'd like to have some advices:

6) are ranged weapons worth their points on the chaos dwarf infernal guard? I think GW or HW+shield are better since dwarves have poor BS, and even if hailshot blunderbusses are nice for the "no-penalties" rule they still hit at strenght 3 and have a 12" range. Fireglaives would be better since they have better range and strenght, but they will often hit on 5s, and since both the options are not cheap i wonder if cannons are enough to soften up enemies before killing them in close combat with GW or block them with 3+ armor save and 6+ parry to flank them with some other stuff

7) are chaos dwarf infernal ironsworns worth their points? I don't think so because CD have better special choices IMO, but i could be wrong
