Auto-tagging MP3s
Solution 1:
MusicBrainz Picard
For something different check out MusicBrainz Picard.
It's cool because it will identify MP3's based on a 'audio fingerprint' compared to their database, so you can figure out songs that are missing all tags, or that are mis-tagged.
I haven't found anything else that works quite like it.
That plus a decent tag editor/renamer/organizer (ie: Tag & Rename, or EasyTag) and you're set..
Solution 2:
I'm using those two programs for all my tagging needs, MP3tag is my first choice, EasyTAG for its support for FLAC/APE.
Mp3tag
Mp3tag is a powerful and yet easy-to-use tool to edit metadata of common audio formats where it supports ID3v1, ID3v2.3, ID3v2.4, iTunes MP4, WMA, Vorbis Comments and APE Tags.
It can rename files based on the tag information, replace characters or words in tags and filenames, import/export tag information, create playlists and more.
Mp3tag supports online database lookups from, e.g., Amazon, Discogs, or freedb, allowing you to automatically gather proper tags and cover art for your music library. Rename files based on the tag information and import tags from filenames.
Mp3tag is freeware.

Solution 3:
Winamp
I've had a good experience using Winamp for this process. I did try some of the others, but I wasn't get the results I expected.
There's a blog post walkthrough on how to use it here.
But basically in the Media Library having loaded your MP3s right click and go:
Send to -> Auto Tag
