Shared Borders in Front Page 2000?

[atomic]

It took me a while to get there but I've just published a test page for my site. It's at -

http://www.mohawks.pwp.blueyonder.co.uk/
(Click on 'Coming Soon')

I'd appreciate your help on the following:
I want to keep the mini-gallery exactly where it is on each new page.
However, I want to use the space on either side eg. to place a navigation bar. It was also be good if I could use a bit along the top for my logo etc.
I don't want to use frames, I simply want to utilise the space I already have, but keep each page layout the same.

I use FP 2000 and was looking at shared borders, which seems a good option. However, the Shared Borders option is unavailable (in grey)for some reason so I can't even try it which is a shame!
Or should I continue with the tables: if so, how do I combine what I've already done?

What should I do?

Think I may have the solution so I'll leave it at that.
Thanks!
