<p>What are the steps to estimating using function points?</p>

<p>Is there a quick-reference guide of some sort out there?</p>

I took a conference session on Function Point Analysis a few years back.  There is a lot too it.  You can check out the
Free Function Point Training Manual
online, the
Fundamentals of Function Points
, or I suspect you can get a book on it at a computer store.
You might also check out the
International Function Point Users Group
and see if they have some resources or a local meeting for you.
