Hey Garry, I asked the same question about wordpress plugins
Check it out, everyone had some great responses!
Lately, I've been using admin page treeview and advanced custom fields. I highly, highly recommend both.
For SEO, I usually steer away from plugins and prefer to code with php based on the page uri or title. Sometimes for meta descriptions, we use custom fields. Most of the time, if the site is 50 - 1,000 pages, we just hard code everything using php functions and variables... Perhaps I should post a Youmoz about that. Sound interesting?
