Is the achievement Vul Throttle doable in the solo areas?

How do I get the quests Voided Responsibilities & Void Studies and Coarse Work?

Any help is greatly appreciated!

Vul Throttle requires doing some heroic quests. The two mentioned above are the end of the two heroic lines.

Is there a wiki quest write up somewhere? I can't find anywhere.
Are these even doable for decorators who don't focus on group content or adventure, or did we get screwed again?
