@lhungril: Thanks for the input. I especially like the "don't resend the welcome email if the customer's already logged in" ... that's intuitive!
Regarding the placement of the "Resend Email" function, I've currently got that imbedded as a "sub-task" of the Add Customers tool, with an option to reset their password. Let me know if this works for you. There's a screenshot that's part of the plugin's zip-file (I would include it here, but I think it will wind up too small to see).
