Cleanup formatting of wordpress layout with Simplepie widget

Existing wordpress Aggregator 1.0 theme by Templatic. It uses an 'Aggregator' widget ([login to view URL]) that is a Simplepie multi RSS feed. 1) I want to change the format (font size etc) of the Aggregator widget output. 2) There are also formatting issues with the text/html widget (used for adsense and twitter-widget scripts) and how it interacts with the Aggregator widgets (overlapping output etc) 3) the length of the page does not accomodate the text widgets (ie. they overshoot the footer) Overall I want to have the site look more like the [login to view URL] format Bids without text or only links will be ignored. target website: [login to view URL]
