1. Vue imports .pz3 files, including animations.
   There's also the option to "host" a .pz3 file, which means you can adjust the .pz3 in Poser and the adjustment will be incorporated in the Vue scene.
   You have the option to import the materials (and tweak them) into Vue, you can also choose to use the Poser shader trees. In the latter case, Firefly will be called to render the Poser elements during the Vue render.

2. Vue is not a modeling application. You can do a little with metablobs and booleans, and that's about it. Rigging: you can do the equivalent of non-bending prop hierarchy "rigging", you can link objects hierarchically, set their pivot points and rotation axes. No full rigging like a Poser figure.
   Animation: yes. You've got a timeline, you can do keyframed animations.
   A nice option is combining a Vue animation with a Poser animation: animate a walk cycle in Poser, import the animation into Vue, and have the walking character follow a walk path in the Vue environment. Works pretty well.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
