You sound rather desperate, but I'm not sure why. I've been using cperl-mode for years and I've never used any of the features (aside from #8) that you describe! As far as #8, if you're using a recent Emacs (21.1.1 here) you can use the customize interface to change fonts and colors. Type "M-x customize-group" in the minibar and then enter "cperl-faces" to go to the screen where you can choose cperl-mode's fonts.

As for your other questions, I suggest you go to the source. Find cperl-mode.el on your system (you may have to install the Emacs source pack to get it) and dig in. There's lots of information in the comments that isn't in the documentation. If you find the features you're looking for then you're all set. If not you can add them and contribute them back to the community.

As a final note, I've always found the folks on comp.emacs to be exceedingly helpful and knowledgeable. Once you've done your homework you might consider posting a few questions there.
