Iconomy also uses H2 which is a more localized, which works without Mysql, database function. In the config.yml make sure your settings are setup for H2 (easiest way to do this is to let the plugin repopulate the file for you if you delete that config, or extract it from the *.jar, H2 is a default setting for Iconomy, however if your menu options are working you might want to check you permissions to make sure that your set to a * permission node. Also your version of craftbukkit will download the required library to use H2 databases. Use the defaults in the zip you downloaded and you'll be fine.
