Well i for one dont fully understand the questions
1 setting up a password system for <ip>etc
What does this mean, its like asking i need help setting up email for <ip>
Do you want to setup password access to server manager for more users, do you want to set up users generally etc etc
2 if you want help getting a domain name i can sell you one or do you mean something different
3 now this is better, whats wrong with it
4 you can login from the console of your sme server or use putty etc from windows if its setup on the sme
