i'd guess that, assuming you DID copy .bashc and .bash_profile from /etc/skel or another user, that they do not have the correct access rights, and consequenetly the global /etc/bashrc file which would normally set the prompt, path etc could not be accessed. try chmod-ing them to the right name, assuming they exist in the first place. same might be required for the directory you created.
the "useradd" command is there for a reason...
