Do I install all the mirrors or just one?

OK, let me simplify this for you....
Download ONE copy of the file from any of the Mirrors (a mirror is just another copy hosting the same file).
Copy it to the root of your SD card (in Windows this is generally the second drive letter that appears when you plug in the USB cable and select Disk Drive), or download it directly to your phone and move it to /sdcard/ext_sd/
Rename the file to PH98IMG.zip, case sensitive
(an extra measure of safety here would be to use a utility like ES File Explorer to verify the MD5 Sum matches what Android Police says it should be)
MAKE SURE YOUR BATTERY IS AT LEAST 80% FULL BEFORE STARTING!!!
Power off the phone completely...
Power the phone back on holding VOL DOWN + POWER until the process begins then release the buttons, it should do so automatically with no additional input from you. It takes a while 20-30 minutes to complete, it will restart several times but should eventually take you to the setup screen, if not pull the battery after 30 minutes
Power up normally and let the phone boot up completely, do NOT go through the setup process. Power off and repeat the last step, let it flash the file again (this is generally accepted as the best method even though it is not in the instructions on AndroidPolice), it should then reboot and you can proceed through setup like normal.
Once everything is good, delete the PH98IMG.zip file from the SD card so as not to accidentally flash it again, wiping your phone.
If this sounds like too much, there is a step by step RUU executable for Gingerbread that is an application run on your PC and it prompts you through everything, even more foolproof, but will require you let the OTA go through afterwards to get ICS. If this sounds better I will link you the info...
