If the data is really valuable, don't touch the drive and get a professional
data recovery company to recover it for you. If that is too expensive, then
you can try somne tricks yourself, but they could easily make it much harder
(and possibly costly as well) if you end up going to a professional later.
In particular you might try looking at freezing the disk drive to get a
little more life out of it. There are instructions on how to do that that
you should be able to find with google.

Running fsck on ext3 is normally fine. You might not want to do it on
a disk containing the only copy of your data though.

I think having an image of the bad drive (as best you can obtain) as a plain
file on the new drive would be best. You can make other copies easier that
way. Once you've done that you can copy over to a partition and try to use it.
