Creating an interacrive website tour

Basically what I am wanting to do is create a page or pages that will walk the visitor through my website. It gives them a task to do and a pop up that explains the steps to go through.

I have found these 2 scripts but wondering if there is anything better that has more documentation with it.

Anyone know of anymore out there that can do this and that I can see more documentation on how to install and everything?

I quite like jQuery TourBus, which is quite well documented.
