Chatframe padding and Editbox background

[Urtgard]

I started to do some minor edits on my ui. But I got two problems with the chatframe.

1. The text sticks at the border. I want a few pixels space between text and border. How can I get an effect like padding in CSS?
2. How can I remove the original background of the editbox? With SetBackdrop I just add an extra border.

Ok, this should be able with

ChatFrame1Background:SetTexture(background)
ChatFrame1Background:SetPoint("TOPRIGHT", 10, 10)
ChatFrame1TopRightTexture:SetPoint("TOPRIGHT", 5, 0)

and so forth.

Doing this in lua feels a bit clumsily though. Is there a way to use a modified FloatingChatFrame.xml, which I got from the Blizzard UI Pack?

After some more testing, this is what I got in combination with Prat:


What do you think? Any ideas what I can do with the FriendsButton?
Would be nice, if someone could check the code for mistakes: http://pastebin.com/q6HQiUDG
