This. Also, it doesn't hurt to get a hold of a proofreader/copy editor who can help you with rewrites and proper sentence structure. You want to come across to those who issue grants as someone who is well-read and thoughtful. (Trust me, disco. Proper grammar, spelling, sentence structure, et. al are incredibly important so don't slouch on these.)
I've also found this website for when you actually start writing it. (It doesn't have the form you need, but it does tell you how to approach writing the proposal.)
