I had a layout looking just as I wanted it before the client decided that they wanted some rotating images on a couple of the sections, unfortunately this meant that I had to take the sections out of the containing div and do quite a bit of testing and tweaking to make everything line up nicely again, at which point the slideshow feature worked fine (and it is another excellant feature that is so easy to use in mojo!)
Unfortunately doing it this way expanded the amount of markup quite considerably over what it had originally been - this is partly due to all the css being inline at the moment while I was testing the layout - I'll move it all into the css files once the 'ready to go live' version of the site is complete.
The questions are - is it possible to use the slideshow feature on 2nd/3rd and if not is there a better way that I could have achieved the same result i.e. is it possible to call the jquery function from the html and would that have been a 'neater' solution or would this way be the best solution once the css has been moved into the css files? The only other slight issue I had was that at the top of the page were some mojo-tabs (great feature) and when I went into the editor all the content overlapped - hence the comment below where I used a big margin to push it down to take advantage of the easy way to add links etc).... on a similar note it would be great if the html editors preserved the format in the html window to make it easier to seperate divs etc - don't suppose that is an option I have missed is it? 
The relevant markup ended up as:
<!-- Comment out div below - added to make editing in html editor easier or content crosses over with content above
