As for the tab width, my initial suggestion doesn't do
what you want.

As for tabs (instead of spaces), I don't get tabs,
even with

    emacs -Q file.pl

Are you sure you get tabs?

Also, this works for me:

    (defun my-init-perl-mode ()
      (setq perl-indent-level                2)
      (setq perl-continued-statement-offset  2)
      (setq perl-continued-brace-offset     -2) )
    ;; (my-init-perl-mode)
    ;;                   ^ evaluate here

And I don't need to restart Emacs to get it to work!

However I can think of one more thing.
After evaluating (my-init-perl-mode), say that you
have a piece of Perl like this:

    sub setup_db {
        print BOLD, RED, " Type ", YELLOW, "y", RED, " to reset database: ", RESET;
        open(my $in, "<-") or die "setup_db: cannot open stdin.\n";

If you put point on the second line and hit TAB, it
will work. If you put point on the third line and hit
TAB, it won't work because it will look at the line
above for alignment.
