There is no way to easily convert PDF to Word (I've made a living out of trying to do this for the past 4 years).
What you can do is extract the text, extract the images, and then re-assemble the whole lot together, either manually or using some of the many tools around. If you are running a Linux system, take a look at these

All "free" (open source).
Also take a look at www.wizards.de - Frank Siegert's PDF processing tools (RIPs and extraction tools).
