With the time crunch that you have, I must suggest that you need more help than you can get here. You should call your vendor now and get an engineer on site. Or hire back some of your laid off experts for a few hours.
For us to help you, we will need to know more. What hardware do you have? What version of unix?
My best guess is that you really have a bad disk and the disk that is bad contains your root file system.
The "wd: ERROR..." seems to be an error message from a disk driver. The controller and device numbers id which device is broken. Block 29 sounds like a block that should exist. A very large number might have meant that the driver was asked to read a non-existant block.
The "hd: Warning" is a bit of a red herring. The system tried to allocate an inode but it failed due to a hard disk error. If the disk was readable, you would probably find that you do have inodes left.
The "-sh: cannot make pipe" tells us why an inode was requested. It's been a long time since I've seen a version of unix that used file system based pipes. I didn't know anyone still did that. It will be interesting to learn what system you are using.
I think that you will probably need a new hard disk. Then you need to re-install the OS. Then you need to load your backup tapes and get the system to the state it was in during your last backup.
You are getting far enough into the startup scripts that the shell is attempting to run. That means that there is a good chance that you can mount your fried disk in read-only mode and have a decent chance of pulling some files off of it.
Bear in mind that this is all guesswork. I have never seen a system like yours and I have very little to go on.

e2undo
E2UNDO(8) System Manager's Manual E2UNDO(8)
NAME
e2undo - Replay an undo log for an ext2/ext3/ext4 filesystem
SYNOPSIS
e2undo [ -f ] [ -h ] [ -n ] [ -o offset ] [ -v ] [ -z undo_file ] undo_log device
DESCRIPTION
e2undo will replay the undo log undo_log for an ext2/ext3/ext4 filesystem found on device. This can be used to undo a failed operation by
an e2fsprogs program.
OPTIONS
-f Normally, e2undo will check the filesystem superblock to make sure the undo log matches with the filesystem on the device. If they
do not match, e2undo will refuse to apply the undo log as a safety mechanism. The -f option disables this safety mechanism.
-h Display a usage message.
-n Dry-run; do not actually write blocks back to the filesystem.
-o offset
Specify the filesystem's offset (in bytes) from the beginning of the device or file.
-v Report which block we're currently replaying.
-z undo_file
Before overwriting a file system block, write the old contents of the block to an undo file. This undo file can be used with
e2undo(8) to restore the old contents of the file system should something go wrong. If the empty string is passed as the undo_file
argument, the undo file will be written to a file named e2undo-device.e2undo in the directory specified via the E2FSPROGS_UNDO_DIR
environment variable.
WARNING: The undo file cannot be used to recover from a power or system crash.
AUTHOR
e2undo was written by Aneesh Kumar K.V. (aneesh.kumar@linux.vnet.ibm.com)
AVAILABILITY
e2undo is part of the e2fsprogs package and is available from http://e2fsprogs.sourceforge.net.
