current state

thanks for the css rule. Please go to this new link:
index.html

1. I rebuilt both nav bars to see if the problem was with something that i did. I believe that i now have the class of current. i don't see it working, nor do i understand how it could. i understand how it would if i assigned the body and id and included the body id in the class of current or if i set a parameter and added a conditional expression to each link.
2. how do control the fact that my about button the hor nav runs into the graphic in the bkgnd? how can i have each button a different size controlled by the text inside (padding - margin)? Can i delete the pixel width for the item and control it another way?
3. each time i go back into "edit" theme of any menu for this site, i get another css and js file. these files have incorrect paths to them (missing the ../). i have been deleting them from the source code. could my problem be the way i have my site set up right now? for now, i have a folder called "newSite" where i am saving all my new pages. my templates are up a level in my site root. could this force menu writer to add new css and js files?
thanks

UPDATE:

Please go to the following link:

My side nav seems to be working as expected as far as the current page function goes. Please note that my horizontal nav is not. Can you please give me some advice what I need to do to fix the problem. I see and the css rule controlling the current page, but am unsure how it "knows" what page is current. Also, I wanted my horizontal nav buttons to have different widths based on the text so I removed the pixed width and used padding. Will this create any problems with browsers? I am understanding how menu writer works. I am still experiencing the additional js and css each time I edit the theme. I am removing it each time.
thanks so much,
Lisa
