Navigation Customization -- consolidating navigation bars, using cufon, and changing the background

Hello,

My current theme was built custom, but I'm wanting to migrate to the Buddypress Daily theme (either temporarily or permanently -- depending on whether or not I'm able to customize to my liking). Regardless of whether or not it works for me, I LOVE the theme and am very impressed. Thank you for your hard work.

On my current site http://thedailygetup.com, each category tab in the navigation area is a different color, and the font is generated using cufon. What I'm wondering is:

How I can get the navigation area of my Buddypress Daily site (I'm using http://shadyfacebook.com to practice) to look and function the same way my current site does?

I've been able to get cufon working, but I am unable to adjust the text, background and hover colors, and the cufon font size.

Can this be accomplished using just simple css adjustments? Or do I need to change any of the core php files?

I would also like to consolidate all navigation components from the information bar, the breadcrumb navigation bar, and the page navigation bar into one or two lines. I saw directions in a previous thread, but was unable to get it working and thought that I may have to do something differently.

Any help would be appreciated!

Thanks.
