Roll Your Own - Tabbed Menu issue

Hi All,
I am working on a clients website which is very information heavy. Trying to make tabbed areas to limited the amount of space taken up.

I went on themeroller and got this:

Which is great. But when I try and use the files I downloaded I have had a couple of issues.

1. Accordion
http://www.mason-uk.co.uk/flexible-pipe-connectors3.asp
This is the page I am testing the code on. To see it scroll down to the bottom.
The drop down DIV's seem to have a lot of dead space beneath the info. and the related products are severally warped (the divs are too big vertically)
 IF I click inspect element I can see that the jquery seems to be adding inline CSS to my divs. When I try and overide this by putting inline css (or external file css) it doesn't make a difference.

2. Tabbed Menu
http://www.mason-uk.co.uk/flexible-pipe-connectors4.asp
This is another option I've been working on. But it doesn't seem to work at all. Even though I have copied over all the files I downloaded from the website...


Any ideas?
Thanks so much
Rich
