Use Expect. Expect is a tool for automating interactive applications such as telnet, ftp, passwd, fsck, rlogin, etc.

I afraid I can't help you on that. May be someone else.

If you consider Perl, there is nice modules available for manipulating the passwd and shadow files. Such as:
Unix::PasswdFile - Perl interface to /etc/passwd format files

Passwd::Linux - Perl module for manipulating the passwd and shadow files

These modules are available here.

Fixed Line

The easiest to circumvent the password thingy to is to paste lines into the /etc/passwd with a fixed string for the password (using a known 'default' password). Then you run a passwd -f afterwards for the user that he/she is forced to change password at first login.
