How...let me answer that back with a question or two, so that I can give you a better answer.
What's your level of comfort with the Poser/Studio file hierarchy? What are you interested in making a texture for and where did you get it?
As for the props- depends on what kind of props they are.
Clothing kind of works, but needs a bit of adjustment and for some poses, a lot of adjustments. Other props, like weapons, hats, helmets, tools, etc should work just fine, but if they are parented to the figure, they may need to be moved just a bit to fit the location properly.
I'll be online all day, so should get answers back to you fairly quickly.
