There's a application that I use on my AT&T Treo 750 called Pocket Express. I think the premium version is currently available for free from the AT&T media mall website.

It's the one stop application that you are talking about and has everything from news, sports, stocks, movie info.

Here's a link to download it from the AT&T media mall:

Anybody else have any experience with Pocket Express?
