If you statically assign ports to the Directory Service and IS, then open those ports on the firewall, you should be good to go.  As ritupatel mentioned, you will need to open port 135 RPC end point mapper.

Many.  This is a security nightmare.  Unless you have no other options, I would avoid this like the plague.  Look into VPN through or terminated on the PIX>

RPC?  Or SMTP?

You need to disable the mail fixup(MailGuard) on that Pix firewall in order to let SMTP mail come into your environment.
