There's a lot of good information on the IRS website and in this
flyer
.
Maintaining your status isn't terribly time intensive if your organization is already operating as a charitable org with good practices, both financial and operational. Most of the IRS rules are the things you are supposed to be doing anyway. It might be worthwhile for your treasurer to fill out a 990EZ whether required to file one or not. It's good to see how the IRS wants you to be able to report income and expenses and may change (slightly) how you keep records.
Below is a SIMPLISTIC list of the key items for consideration. Visit the IRS website for details.
