I've installed SP6a a second time and of course I overwrote the previous SP uninstallation files with SP6a's. Is there a way to manually or otherwise uninstall the current SP and get back to an older one (say SP5)?

The easiest way is to re-install NT again as an upgrade and install SP5 afterwards.

You cannot uninstall the SP6a unless you chose the backing up of earlier SP. Always wise to backup previous install when upgrading service packs.

Good luck

While applying a service pack you get an option to be able to revert to a previous service pack. As long as you checked that box you can just go to add/remove programs in control panel and remove service pack6a there.
