I am wondering how I change my subcategory fonts?

I have looked through the stylesheet a million times and i can't figure out what everything means. I have tried to download Mozilla and it didn't work for me.

I have subcategories under subcategories.

I just need help on where to change the font for all the menu items and descriptions.

Also - can anyone tell me how to remove the huge space between "welcome guest" and main_page?

Any comments on my site would be more than welcome as I am a new zenner and completely a novice .

thanks so much
