Hi Joe,
You may want to read this FAQ: http://www.mojoportal.com/faq.aspx#fonttoolbars.
Secondly, if you decide you want to have the font size and type options in your toolbar after reading that FAQ, you can follow the instructions here: http://www.mojoportal.com/customizing-the-editor-toolbars.aspx.
I suggest that you do not put these options in your WYSIWYG toolbar because it will mean a lot of work for you in the future if ever decide to change skins. The best alternative is to create CSS classes with the font styling that you want and then put those CSS in the Content Style Template system.
HTH,
Joe D.
