I've had a considerably better success laying out pages and manipulating graphics with MS Publisher over Word.
See if you can use an older or "evaluation" version first, before investing in it. Also, if you are used to the pre-2007 MS Office interface, do not switch to 2007 before familiarizing yourself with the new ribbon design, as the learning curve may be quite steep and hamper your main objective.
If you will have an online version as well, let us know where we can see it when published.
Good luck!
