I'm a newbie with jQuery. Please help with Tabs

I have a page set up using jQuery UI tabs. Here's my issue. On tab #4, I'd like to link to an outside page, how do I do that? Now, it simply opens the page within my current page, making it VERY ugly all the way around.

Second question, I have some scripting that needs to be loaded just before the /body tag. When I load it, none of my tabs work. Any ideas on how to fix this?

Thanks in advance!
