Edit color/style of main nav menu on blogs-mu theme?

Hi all!

So this is my first post, but won't be my last...

The Blogs-Mu theme rocks!

Currently, I am trying to locate (and edit color) for the hover/active
links in the main navigation bar. Although I thought I had seen the info,
I have searched, and searched....to no avail this time 'round

Live demo of issue:

WP 3.0.4

I have already made a couple of successful edits by adding
them into child-style.css, and suspect that the "place to add"
would be the same in this scenario?

I am not a coder - but comfortable making edits safely
with a bit of pointing in the right direction on this one...
