Theme development

From a CSS amateur:

I have text showing in nodes and in added blocks that makes use of bullets. Especially in blocks, width is limited; I'd like the bullet items lined up all the way to the left, to prevent lines breaking. But Garland gives me some serious bullet indentation.

Scanning style.css, I can't find the appropriate control. I chased down some ideas in CSS resources, and added this to the beginning of style.css:

ul {
list-style-type: none;
margin-left:0px;
padding-left: 0px;
}

I'm setting up a drupal site, with a single code base, but multiple sites..

I've just run into my first snag as far as theming. I keep all the themes in /public_html/themes/

I wanted to create a custom favicon.ico and logo for each site.

For the logos, each time I upload a custom logo, I can point to it in the theme settings /files/siteacustomlogo.gif /files/sitebcustomlogo.gif and upload those files through FTP.

but what about favicon.ico?

First, here is the site:
http://masstvonline.com

Right now, when you click on "Comedy," it expands into the two stories. This is a good start, however, I wanted to know if it is possible to make it so that Comedy only expands when it is hovered over, OR if it could collapse when one of the stories is clicked on.
I'm pretty sure I need to change the .active state of something, I'm just not sure what...is it in drupal.css? What should I do?

Any help would be greatly appreciated!

I am wondering if anyone has converted the Zen them for use on right-to-left language websites. I am submitting a proposal to develop a website that will be multi-lingual, featuring English and Arabic. I will most likely need to convert a theme (hopefully Zen) to right-to-left format. I haven't looked at how to do this yet, so I am just testing the waters to find out if someone is working on this, or if I will possibly be going it alone. If I get the job, I look forward to perhaps contributing in some way to such a project.

Is this poosible and I have a another question what do I need to do/get to start my owm theme without any experence ?

Okay so Here's the problem:

I'm using the Garland theme and I've created several taxonomy themes based on the Garland (only changes have been to the colours)
