1) Control panel, Add/Remove Programs, find Add/Remove Windows components on the left pane. A new window pops up; go to the bottom and you will then uncheck Terminal services.
2) Not sure what you mean but you cannot change the password on ccmadmin page. There are two sets of accounts in a default ccm install; first set is the windows accounts such as the administrator, and the second set are the ccmusers whose accounts are created in Dc Directory. You will notice that the accounts that you create in ccmadmin page are not created in the windows local accounts. If you are logging on to the ccmadmin page using windows\administrator account, you will change the administrator password by using local computer management applet, or doing Ctrl-Alt-Delete after logging on locally at the server.
