Editing The Subscribe Page

Is it possible to edit the banners (for itunes, rss, etc.) on the subscribe page created through the plugin? I know you can edit the text, but my website is themed in black and white and I was hoping there is a way I can make all those buttons black and white as well.

Here is my subscribe page:

Also, in the subscribe page can I edit where the RSS link is pointing to WITHOUT changing it everywhere else? I just want to change it for that one banner on the subscribe page (and side bar widget) so it points to my feedburner feed page as opposed to the unattractive xml page.

Appreciate any help!
