Bad Pool Header blue screen - can't load Windows

I hope someone can help.

 

I had an IRQ conflict and brought my Inspiron 8600 to work where tech support tried to help me resolve it.  Thought we had, and downloaded SP2.  When I took it home, I discovered the IRQ conflict hadn't been resolved and determined it was due to the wireless card.  I searched for a new driver or patch and downloaded something from the Intel website.  After installing the patch, I was asked if I wanted XP or Intel to run the wireless card - I chose XP.

 

Upon reboot, I got part way through Windows loading and went to the Blue Screen with a Bad Pool Header error.  I cannot boot up to Windows except in Safe Mode.  I have tried to restore to last known working configuration, but it didn't work. 

 

I haven't backed up in a while and would like to save my documents, photos and music files before I screw up the computer completely.  Then I hope to fix it.  I went to Firedog and they want about $300 and 1 week+ to backup and fix.  I'm hoping someone here can help me either back up the files myself, or backup and fix the machine both.

 

So my questions:

1) My computer won't recognize USB ports in safe mode, so I can't use an external hard drive or USB drive to save to - will I be able to write to a CD (I don't have one here so haven't tried yet)

2) Have not tried Safe Mode with Networking yet as I am loathe to keep adding error files to the computer - anything I can do with this? email all the files?

3) What else can I do to back up the files or am I stuck with Firedog? 

4) If I uninstall the Windows SP2, will that remove the problem? If I haven't managed to back up, will I lose my files?

5) If I install Windows completely again, I assume that would fix things but I would lose everything?

 

Any other suggestions?

Thank you for your help! Thank goodness I have access to another computer through work (which is how I'm posting this)
