If you are planning to deploy it internally only, the SPS CALs are cover
with the SPS server  license.

As for SQL, if you purchased the per processor license, the CALs are cover
as well.

For external client connectivity, there should be pricing of SPS external
CALs per front end server at around 2000 US dollars. (You should verify
that)

Is that entirely accurate Dave? With SharePoint deployed  internally, you
still need 3 CALs:

1 for SQL
1 for Windows Server
1 for SharePoint Portal Server

SQL does have per-processor licensing, so you can purchase that and avoid
buying individual CALs but both Windows Server and SharePoint require client
access licenses for each user/device.
