Hi,

You can use the standard styles for applying a background and change the font appearance here is some help about this:

About the clearing question you, it seems that you want to clear all styles that you set, but you didn’t mention is there any difference where (in the formatted text or not) you type something and do you want to clear formatting only for the typed text or for the whole content.

Here is some help how to clear specific style:
http://help.infragistics.com/Help/NetAdvantage/NET/2008.2/CLR2.0/html/WinFormattedTextEditor_Clearing_Specific_Styles_from_Formatted_Text.html
I make sample which clear the styles that you mentioned by typing in the formatted editor text area.

You also can look at the sample project in your Sample Browser under section “Commands and editors/ToolBars/Ribbon with Formatted text editor”.

I hope this information is helpful.
