In my opinion, the meta tags likely had little to do with your PR drop. You might get fewer results if you are filling the meta tags with keywords, and it looks spammy to google.
A multitude of things can cause a PR drop, and it can be difficult to narrow down the reasons. Post a link to your site, and I can give you some clues as to why it happened, but I don't work for Google so I can't say for sure.
A general rule on Meta tags: Use the description tag only, and use it to create your own abstract beneath your link. Don't stuff it with keywords, design it with the search engine user in mind. Try to create text that will entice someone into clicking through. That's really all you should do with meta tags anymore.
I'll do a write up on this soon. Like I said if you want to post the link, I'll check out your site and let you know what I think.
