I thought I would add this additional information on writing grants. The first link is for the NEA which gives you email addresses for state and regional arts councils where you can write for more details on what they might be offering.
This second link brings you to a site that is a wealth of info on writing for grants and should prove very helpful if you have the time to go through it.
This last link is for my Canadian friends of which I have a few. I wanted to make sure they were included as well.
Happy writing to one and all!
