We can always provide better answers for specific questions :).

Sounds like a good job for a script, but I think you can save yourself
a few steps here.

This should be done automatically when adding the user.
useradd <name>

Don't know the details here.  Default setup is user is in his own
group.  You can specify all sorts of parameters with "useradd"
man useradd
is a good read.

> 3. Create a public_html directory under their home directory

Anything you place in the /etc/skel/ directory will be placed in the
user's home directory when it is created with useradd.
mkdir /etc/skel/public_html

> 4. chmod home directory 755

I would assume you could set this behavior in some config somewhere. 
Fedora is setup pretty tight (perms 700) by default, but I know other
distros are more loose.  You could do this is one fell swoop after
you've created all your users if you cannot find a config for it:
chmod 755 /home/*

> 5. chmod public_html directory 755

I don't recall how /etc/skel/ works with permissions, but I would
think it would keep permissions the same.  A quick test seems to
indicate that.
chmod 755 /etc/skel/public_html/

> 6. chown home directory -R to user

Again, should be automatic with useradd if you don't manually create it.

> 7. chgrp home directory to apache

I don't get this.  Perms of 755 are world readable and executable, so
why make the home dir group apache?  If you want all your users in one
group, I suggest using a group called "users"  You can set the default
group with useradd as well if you really want to change it.  It will
set the user's group and the perms for the home directory.  By the
way, chown can set the group as well.  Either of these works.
chown user:group
chown user.group

Looks like you gotten some good feedback here already.  If you still
need to add samba users, take a look at smbpasswd which can add users
from the command line (and thus could be used in a script).
man smbpasswd

> everything should then work

You don't mention setting up a default password.  You can do that with
the -p option to useradd.  Note this takes an encrypted password
(again, see "man useradd").

I certainly recommend a script, and use some of the above tips.  Then
you just create a file with the list of names, run the script, and you
should be up and running.

Is a great site about bash shell scripting.  Basically, I think for
1-7 all you need is a carefully constructed "useradd $student" line
and perhaps the "chmod 755 /home/$student/" in a for each loop.  Even
without the script, 1-2 commands per user is better then 7 steps :).

Looks like you got an answer here.  I've never dealt with anything
like that before.  Probably will someday.
