I just wanted to thank all of you who helped me with this problem.
dd_rescue was the ticket. I used Knoppix and dd_rescue to copy the
entire /dev/hdf drive to a brand new drive. Took almost 36 hours to
copy 250GB. After that, I replaced hdf with the new drive and
rebooted the machine back to FC4. I then mdadm --assemble --force
and then mounted the drive. All the data seems to be there (or at
least the data I cared about). Next, I installed a new drive to
replace the first failed drive (/dev/hdh) and then began the
rebuilding process. Everything seems OK for now.
Thank you all, again.

OK, so 952 errors (about 450k) and 25+ hours later, I have a copy
of the hdf drive on a brand new 250GB drive thanks to dd_rescue.
I haven't tried swapping it to the array. That's the next step. I
imagine, I'll be able to mdadm --assemble --force and have it take
the 4 drives into the array. Dare I mount it after this or is
there some troubleshooting I should do before a mount?

I bought two extra 250GB drives - I'll try using dd_rescue as
recommended and see if I can get a "good" copy of hdf online.
You might want to use dd_rhelp:

Having used both dd_rescue/dd_rhelp and the gnu ddrescue in anger,
I'd
suggest gnu ddrescue.
