Twitter widget problems

[Romea]

I installed the Twitter widget from Twitter's website: http://twitter.com/goodies/widget_profile. Everything works beautifully, except my Streamline theme's CSS widget fonts codes are overrriding some of the widget's fonts.

Here's my site with a page with the Twitter widget on it: http://www.eventuresincyberland.com/my-blog/blog-posts/

Here are the 3 font problems:

1. The widget's two heading fonts should be Arial. Right now, my name is showing up in Georgia. I would like to switch it to Arial.

2. My moniker is all uppercase. I want my moniker to read CyberlandGal (with that capitalization and without the transform: uppercase). Thankfully, my moniker, unlike my name, is showing up in Arial.

3. The body text of the widget is able to override the Streamline theme's font codes. Unfortunately, in this case, I would prefer the body text to be Arial, like my other widgets' text. Right now, it's Verdana, and I would like to override it, making it Arial.

Can you all let me know what I need to add to my CSS file to make all this happen? I would very much appreciate any information.
