WordPress permalink headache

Hello there

I have been tearing my hair out for ages over a permalink structure problem which I cannot seem to get the right settings for. I was wondering if someone could help and outline the settings I need achieve the following consistent structure:

Home page: /about/blog

Home page (paged): /about/blog/page/2

Post: /about/blog/category-title/post-title

Category: /about/blog/category/category-title

Tag: /about/blog/tag/tag-title

Archive: /about/blog/year/month

If anyone can help then if you would be so kind as to outline the settings I need for: wordpress URL, blog URL, permalink structure, tag base, category base, .htaccess then that would be great

So far the closest I have got is by using /about/blog in the permalinks which gets what I’m after but causes about/blog/page/2 to break.

I have also used other settings to get everything as I would like apart from the archives which are still located in the root i.e. /2009/06 not /about/blog/2009/06

Is what I’m aiming for even possible?

Thanks a lot
Matt
