Setting up Exchange Server: SBCyahoo & Namecheap

I am setting up Exchange on an SBS2K3P with ISA installed.
2 NICS with the Server WAN NIC going to a Cayman 3546 (DSL) & out to SBCYahoo
http://www.netopia.com/equipment/pdf/spec/3500.pdf
SBCYahoo is serving a static connection with DHCP out of the Cayman.
I have registered the public domain with Namecheap.com.
I have SBS2K3 Premium installed & am getting out through the Cayman just fine.

I am WAY confused about setting up DNS, MX, MXE, CNAME & 'A' records.
Do I do this on the NAMECHEAP site (they have what appears to be good host
setup tools) or on the SBSYahoo side ?

I need a little bit of a primer on the what, where and how to enter the info
in order to get SMTP up and running on the Exchange Server.
There is a POPMAIL account on the SBCYahoo side that I want to foward into
Exchange too, but that should be simple enough.

TIA!!!

You do it with whomever is authoritative for your domain's public DNS. First
you need an A record that points to your public IP. Then you need an MX
record that points to that A record. Then you need to make sure ISA knows
how to route/allow inbound traffic from the public to the Exchange server's
private IP on port 25. You don't need a CNAME.
