Some comments:
Windows 2008 has additional restrictions around the storage w/r/t Failover
Clustering. Parallel SCSI is not supported for the shared storage so this
may rule out clustering for you.
As for the highly available file share, you could also use DFS.
With a single storage unit, you are looking at doing SCC (single copy
cluster) with Exchange 2007...but NOT with Standard Edition. Unfortunately,
you'll need Enterprise Edition:http://www.microsoft.com/exchange/evaluation/editions.mspx
I'd suggest that you consider working the existing server (SBS) into the
solution in the end. You could wipe it (after migrating to the new target
solution, of course) and leverage it as a DC, etc...
It sounds like you need some consulting to sort out your equipment vs. your
needs...

Less than 20 person engineering firm. Have needs for:
2+ Terabytes of local data storage
Email serving with local control
Shared Internet access with VPN capabilities
Printer sharing
To date we have used SBS 2003 to fill this need nicely but after a
recent hardware failure and too much downtime, management decided to
invest in a more highly available option. We decided to go with
windows clustering and purchased 2 identical machines from Dell with a
shared storage unit, Windows Server 2008 Enterprise and Exchange
Server 2007 standard.
Now through my search for recommended configurations I find it
confusing on how I need to have this setup. It is not recommended to
cluster domain controllers and Exchange clustering on DMs does not
seem to be supported. I need to find a resource that addresses my
network topology to accomodate a highly available environment from ISP
to end users. Is there a recommended resource for network layouts for
our scenario? Would a Primary/Secondary domain controller with a
hardware fault tolerant NAS be more what we should be doing?
Any direction would be appreciated.
Thanks,

Not having the exchange data stores on the single copy cluster device
in not a major hindrance. We can have each exchange maintain its own
data store and keep it synchronized.
We have SAS on the storage device so that is not a problem.
What I plan on doing now is to use Hyper-V to run a virtual server on
one machine, make it the PDC, make the Hyper-V machines main install a
member server and another identical machine another member server and
cluster the members. They will be file sharing/print sharing clusters.
