We are preparing to Deploy a new Server to our End User (2008 R2 Ent) with Exchange 2010. My question is, If they have approximately 40 physical users, but lets say, 60 Exchange Mail Boxes (Miscellaneous/Sales/Etc.), how many Exchange CAL's need to be purchased?

You will need an Exchange CAL for every "person" that connects to your Exchange. Generic mailboxes do not count against this license.
So, to answer your question, you will need 40 CAL's.
Also, depending on the other servers in our Org., you might also need Windows CAL's for each user connecting to the Exchange box (again, 40 Windows CAL's)

Here is a blog that details common FAQ's but as always, you should consult with a Microsoft rep when it comes to their licensing requirements.
