You'll need to use sendmail's SMARTHOST feature. You'd specify the  
hostname of your exchange server there.

Probably not if you have a somewhat normal installation of Exchange.  
You may already permit access for clients on the local subnet. If not,  
you can permit the IP of your nagios server to relay through your  
exchange server (ESM -> Administrative Groups -> <YOURDOMAIN> ->  
Servers -> <yourserver> -> Protocols -> SMTP -> Properties for Default  
SMTP Virtual Server -> Access -> Relay. Who says Exchange isn't  
easy...).

Configuring nagios to actually send notifications but there are plenty  
of docs on that already.
