I have a client that can only get a dynamic IP from their provider with a 677 router. Can I enable port forwarding if it obtains the public IP from their DSL provider? I plan to get in using DNS2go which updates the changing public IP.
Can I port forward a dynamically changing public address to a private address? If so, what are the command lines?

I have experience with these things and, despite not using them in this scenario I would still say no!! I'd say you definitely need a fixed IP. I would also upgrade to an 827 as they run full IOS and not CBOS which, as I'm sure you know, is basic in comparison. Also the 677 is EOL and ( if I recall correctly) is only software supported for 1 more year - or thereabouts. We are using IPCP as well but for extranet purposes - anything such as you are trying is fixed IP.
