Colouring issues

[Korinth]

Hi to all of you, I'm new to both here and vBulletin.

I have been changing the site appearance to my taste and it is going good so far except for a couple of little problems.

First problem is that the bar with user Cp, Blog, FAQ and go on have this blue edge to it, I cannot get it off, so how do I do this?

Secondly, at the bottom of the board where you see the bars with information such as “all times are gmt” and the “Contact us, Sovin Nai, Admin” and “powered by vbulletin@ version beta 3.7” is a lighter gray, I'm trying to turn it into the dark gray colour, so the bar won't be visible.

The address is http://sovin-nai.org/forums just so you can see it first hand, especially that blue edge!

How do i select a gradient? I have uploaded one for the main background, so instead of putting in #b2981d and that kind of thing, I need to write in the location of the gradient. Tried url/image/gradien/background.jpg etc.
