By stealing all the Dust, the rarity and high demand + the WF's sabotage affecting the delivers of Dust to Vale, caused the prices to skyrocket, supposedly. This hurts the economy and causes disatisfaction. Dust is used for everything, so it does also hurt their capacity to defend themselves.

Buying Dust from the White Fang, maybe he pays them for jobs he had them do but was not involved in, as a way to "smooth" things between him and them, seeing how the WF are very anti-human normally. Being paid for it is at least less "disgusting" than being ordered to do it for a human without any apparent reward.

The collected Dust, would also be used on the train, to make the explosives. Though it's possible Roman didn't know that yet. When he caused the Breach, things were not ready-enough yet. It's possible they were still setting up the explosives.

That's what I think.
