Hard drive crash, music on external drive but no library or playlist backup

Question

I'm guessing this question has been asked many times but I've searched all over the internet and these forums and am exhausted. So I beg for your help.
My computer hard drive crashed. Not sure if I can get the files off it yet or not but will find out this weekend trying to connect it as an external drive with a special cable. All the Itunes music is on an existing external hard drive that works fine. No backups were ever created of the playlists or of the library file on the crashed drive, the external drive, or anywhere else.
I'm using what I guess they call on original Ipod, 25 GB.
The main thing I care about is getting 5 years' worth of playlists back. Most of them do exist on my Ipod, so at worst I could reference them visually there and recreate them in Itunes. But, um, I'd rather not!:)
So if with that information you can tell me what series of steps I should take to try to restore my playlists into Itunes on my new PC, or point me to a link, please do. I'll put my thoughts and questions below if this helps in figuring it out. I would say the chances are that I can't access any files from my old hard drive, but it is possible.
My Ipod also contains most of my songs and playlists, but not all, such as different versions of the same song etc. That is in addition to the external hard drive that all my songs are safely on.
1) If I can access the files on the old hard drive, is there anything there that contains information on the playlists if I haven't backed them up individally? From my reading it seems like playlists are not contained in the library file itself, is that right or wrong?
2) What information is contained in that library file, what does it do? If I can't get it from my old hard drive what will happen if I have Itunes create a new one?
3) I've read that I may be able to get playlist information from my Ipod, but it seemed really confusing and I was uncertain if that was correct. Is that a possiblity? Can I do it by accesing the Ipod as an external drive?
4) Would I also be able to get the libary file from the Ipod if I can't get it from my old hard drive? If the Ipod contains most but not all of my songs, would it be bad to use this file with the complete list of songs on my external drive?
That's about all the questions I can think of, so if anyone can help I'd appreciate it. I just can't seem to find an answer specifically to what happens if your music is backed up but playlists and library are not.

See: What are the iTunes Library files? Both the ITL and XML files keep your Library data. The ITL file is used by iTunes. The XML file is created by iTunes and can bu used in other programs or Imported back into iTunes to re-create your Library. hey are only as good as your last archived backup file (should you corrupt the current Library database file).

These are only in the iTunes Library files (ITL & XML):
Playlists
Ratings
Play Count
Last Played
Date Added
Date Modified
Equalizer
Volume Adjustment
These are stored in the music file itself:
Artist
Album
Song Title
Year
Comments
Compilation tag
Lyrics
Genre
Grouping
Volume Adjustment (a special iTunes-only tag in the file - non-standard)
Composer
Bit Rate (not a tag - inherent to the file itself)
BPM
Kind (not a tag - inherent to the file itself)
Album Art (only stored in the file - not copied to the iTunes Library ITL or XML files)

These links will give you several methods of recovering whatever songs remain on your iPod; some free, some third-party software, some more comprehensive for restoring Playlists, Ratings, Play Counts, etc. Read them and their associated links before deciding on a strategy that works for you. There are many various third-party software programs that will offer a more robust process, or an easier GUI. Do a Google search for them if the links below leave you wanting…

Not directly. You'll need to use the recovery software mentioned in #3 above.
