I've only used them once, because my company doesn't like schedules. That's a long story all together. Schedules are great, though. Only problem is that 3.3 and 4.0 are not so similar in their structure. It's not a simple task at first, but powerful once you get things set up. The first thing you need (<- read have) to do, is get Paul Aubin's book "Mastering Autodesk Architectural Desktop". When you get it, the version I have, chapter 11 starts you in on generating schedules. Until you get it, experiment with property set definitions and schedule data. Once you figure those things out, you should be well on your way to obtaining the results you're after. Sorry I couldn't walk you through it, but schedules encompass so many things. You'd be amazed at what they can do. Dive in.
