Need help configuring theme (GTK2 to GTK3)

view story

http://crunchbanglinux.org – Since moving from Squeeze to Wheezy, i've been trying to get my themes to look the same in GTk3 or as close to as they do in GTK2 programs. I've never really done any real theming, just mostly changing colour codes around and a bit of guessing.Here's a screenshot showing how the theme currently looks with gdebi using GTK3, As you can see the screenshot, the text is black for the description of the package, the shade of red for the top button is also too strong making the text hard to read.Here's a screenshot of the waldorf theme, just so you can see what isn't visible (HowTos)
