Only and advice.

By personal experience, if you do something expecting that it will just 
works, without testing it first or really knowing what you are doing, 
probably a lot of problems will arise.
Every time I needed to deploy something that I didnt know about (never 
have done) and didnt had time to learn and test it (and the time of 
deploy really was critical) I contracted someone to do that part.
If you cant make sure it will work it doesnt count as an alternative.

Yes you really doesnt need a WINS server if all machines are in the same 
network segment, but even for small networks (with an always available 
server) its recommended, that way you will have a dns-like service and 
the clients will not need to broadcast all the time to make name 
resolution works.

wins support = yes, tells samba to BE a WINS server, to make a 
difference ALL clients MUST use it, to not ending up having partial 
views of the neighborhood and resources available. Besides the error 
message, your client shouldnt appear to be using it as a WINS server, I 
dont know if it should work only setting that option and having that 
"node type = unknown" config problem on the clients. About the DHCP 
thing, its only easyer to deploy WINS configuration using it, you can 
specify an address and node type to the clients, but it can be done 
manually too, in each client (the node type only can be changed in the 
registry then, but its not normally necessary, the default not unknown 
value should work well).

No comments, the two samba books are the minimal things that people that 
deploy servers really need to read.

Hmm, not really. You can have home shares and connect to them manually 
without need to be a DC.
