Those 5 things are ok, but no reason to use Ubitquity. Its best used at the moment learning how to make your own commands for future applications - the fact every firefox plugin can be written in ubitquity and customised will surely make the difference. I also wouldn't subscribe to anyones Ubitquity commands just yet since they are a very high secruity risk, as they warn in the tutorial.
