Try this, it worked for me.

(add-hook 'latex-mode-hook (lambda () (setq fill-column 100)))

Any mode that has a mode hook, all that I have seen do, can be set in a
similar manner.  Just specify the appropriate mode hook and the value
that you want the fill-column to be for the mode.
Individual mode customizations have to be done with a mode hook because
the variable fill-column becomes buffer local when it is set in any
manner.  Since the since the mode hooks get executed each time the mode
in invoked, i.e. each time a buffer is created in that mode or you
change a buffer to that mode.

I have the following in ~/.emacs:

(add-hook 'text-mode-hook 'turn-on-auto-fill)
(add-hook 'latex-mode-hook 'turn-on-auto-fill)

I now want to set the fill-column differently for LaTeX files.

This doesn't do anything (I verified with C-h v that the value of 
fill-column is 70, the default):
(add-hook 'latex-mode-hook '('set-fill-column 100))

This gives an error when starting emacs:
(add-hook 'latex-mode-hook ('set-fill-column 100))

What's the correct syntax?

Also, once I've done that, can I set it differently for mail-mode and
