I agree with ronknights. Learn Poser (for example). As your needs expand, pick up additional "tools" to help you achieve the effect you're trying to accomplish. For example, I use Poser and Paint Shop Pro (the latter for touching up some of Poser's faults and an occasional texture). I don't do much modelling so I haven't had a need to pick up those tools. Same goes for commercially available "enhanced" characters, props, textures, etc. in the Marketplace. Learn the basics first and pick up what you need as your experience and needs grow.
