You could make a model sheet then cut and paste. Generally, we do actually draw those things over and over again but if you can minimize it with a model sheet showing the character from various angles and maybe an expression sheet showing the face in various expressions at different angles. That way, you at least have a starting place I guess. Like I said though, in comics, you usually have to draw it over and over again. The latest version of Poser has a "comic" like render option that could help with the background bit. If you can find a model that fits the backdrop you need, you can run it through Poser, do a render and then use that render as a backdrop. Again, it's going to require an upgrade or if you're going to stick with Poser Pro 2010, you may want to hunt down some cartoon shaders that you can apply to objects before rendering.
