problem with customizing header

[Andreas Peter <info@minimag.de>]

Hello list,

I am totally new to DocBook and have some questions about formatting 
several parameters.
My questions are, I hope, really simple:

- I try to customize the header. The header should be as wide as the page.
- the toc is shown twice => I included <toc/> after the <set> element
- I need to remove the word "Chapter"for every <chapter> element in the 
instance document

Is it right, that I change everything concerning the docbook under 
/frameworks/docbook/xsl/params ?

Thanks so much,

Andreas
