Thanks, just a forewarning that there may be a delay until I can address this.
1. Amount field will be removed next version but if you can't wait, I can put together some edits for you to do this in the meantime.
2. If you want to edit the text, edit the language string "block_donateDonate_text" in your admin cp.
3. I've just looked into the possibility of adding an image button instead and it does look like this is possible. Do you have an image in mind that I can test it out with?

That's a bit more difficult now as that widget uses the form helper to build the donation form instead of raw html code you can modify from the template bit. Any changes need to be applied to the widget file directly now.
The edit button being there is a bug which I've logged a bug report for. And I will be very likely removing the amount option from the widget next version due to some conflicts with the next page.
