Check out the Mars Direct proposal championed by Robert Zubrin: http://en.wikipedia.org/wiki/Mars_Direct.
Not only did it involve pre-setting equipment and habitats, it's launch framework was shuttle-derived, thus precluding a need for new (potentially troubled) launch system. Such a shuttle-derived system is reflected in the Direct proposal: http://www.directlauncher.com./
For my money, the whole Ares launch system is a waste of time, money, and effort, too. We could probably be on Mars in ten years if they followed the Mars Direct/Direct Launcher path.
