Done to death?
 

Probably but I'll ask anyway. http://www.the-sps.org/images/smilies/tiphatyj7.gif

Is it possible to add in additional buttons that would normally be standard in CKE, I notice that you can download a copy of CKE from their website so I would assume I would just be patching a file and adding an image, would that be right?

There is a thread here where someone asked for help getting the full editor up when editing Static Pages. I posted what to do in that thread. Is that what you are asking about?

Yeah basically Lynne, although I'm not wanting to add all the buttons, just a few. Strikethrough as an example (without using addon BB codes) :)
