Custom Social Buttons

How do I remove "Be the first of your friends to like this.

This is not configurable if you are using the 'Standard' Layout style. You can switch to Button Count which removes the text and puts the count into a bubble next to the buttons.

Is there a way to upload or change the look of each social button used in the Layout Styles for Content Plugin - Like and Content Plugin - K2 Like?

Each social network only defines some predefined styles, and we can't alter those. The most control you have is over the layout field for all of the fields and then Facebook also provides some unique additional styling options like the verb, color scheme, font and width that you see in the configuration area.

I hope this helps explain the available options.
