Re: Keywords/meta tags, and title of page change..
You have a local copy of all your site files, right? If not, ftp the site files to your local hard drive -- no need to include the images for now.
Then, using a suitable multi-file search tool, search for the meta tags you currently see in the page source as rendered in the browser. That should find the file in which they've been defined. Go there and edit them, then upload that changed file back where it came from on the server.
