Fix and improve word template

I have developed a word template, including custom ribbon which works reasonably well when a document is created from the template. However, when applying to a different document, the colours may change (the colour pallete changes to standard and so colours don't work), and bullets and numbering often seem to go awry. The bullets have a particular symbol that needs to be used but doesn't always appear. I'd basically like the template checked and fixed up so that it works universally across different computers and files without these sort of bugs. I'd also like to understand where these issues have come from and what their solutions are (what solutions you implemented). Requires skill with developing templates and understanding styles in word, including custom UI (custom ribbon) / xml coding. Note that any improvements outside of the above scope can be discussed at such time, but will be generally welcome.
