I have been meaning to post this tip but kept forgetting. If you are looking to create some quantity take-off schedules don't waste your time doing them from scratch!
Autodesk decided to have a whole bunch of really useful schedules hidden inside their "Construction Template". When you start Revit and create a new project chose the "Construction" template and take a look at all the neat schedules!
Oh, and you can simply copy and paste them in the project browser to your new project!
