MS Word is a feature rich word processor, not a DTP package. If you want a simple program, MS Publisher is aimed towards DTP. If you want a powerful application, you'll be looking towards Quark XPress or my personal preference of Adobe Indesign.
Getting things done quickly and efficiently is all about using the right tool for the job. The problem with Quark, Indesign and most other pieces of excellent (Windows, Mac, less so now for RISC OS as it is largely hobby driven) software is that they come with quite hefty price tags for a private or home office user.
