Help Aligning with CSS

I’m new to CSS and having trouble aligning some icons under a logo

The page is http://www.commandcreative.net/rachelbmusic/

I wanted to center the social icons, and the mailing list button under the Rachel B logo – but I can’t figure out what to add to the icons.

I use a bunch of shortcodes from the X-theme (which I don’t like but she wanted) to get the buttons in

Example: [image type=”none” float=”none” src=”http://www.commandcreative.net/rachelbmusic/wp-content/uploads/2015/02/Rachel-B_Logo.png” alt=”Rachel B” info=”none” info_place=”top” info_trigger=”hover”]
[clear]
[image type=”none” float=”left” src=”http://www.commandcreative.net/rachelbmusic/wp-content/uploads/2015/02/48x48_facebook.png” link=”true” href=”https://www.facebook.com/ThisIsRachelB” target=”blank” info=”none” info_place=”top” info_trigger=”hover”]

That’s just the FB icon. I’m hoping to center all of them under the logo.

Help ?
