Welcome to SO!

The problem lies in the definition of the button interface. You're using | to indicate a separator when you should use separator to do that.

Change the line to:

theme_advanced_buttons1 : "bold,italic,underline,strikethrough,separator,justifyleft,justifycenter,justifyright,separator,fontselect,fontsizeselect,separator,bullist,numlist,separator,outdent,indent,separator,undo,redo,separator,forecolor,backcolor",

You can scan through the documentation for theme_advanced_buttons1 here if you like. http://wiki.moxiecode.com/index.php/TinyMCE:Configuration/theme_advanced_buttons_1_n
