OEM Ship Verizon ROM...is this it?

[Gen2ux]

I've been looking ALL over the place. I've searched with this sites search tool and also with Google. I just can't get clarification on this. I got a used XV6700 and it's running bootloader 1.0.0 and had WM5. I installed a cooked version of Helmi's WM6 which is very nice and works well. However, I realized that the Checkpoint Secureclient VPN client I need only runs on WM5 (for now). I'd like to take this ROM back to stock. I found on www.utstarcom.com/pcd/downloads/ they have listed this:

Sunday, December 11, 2005 5:13 PM 37164015 HA_VZW_136_117_01151_SHIP.exe

What do the different numbers mean on here? Will any of them work? What is
the different when it says "WOC" and "SHIP" (i'm assuming ship = shippping ROM)

Any help would be appreciated. It's great how helpful everyone is on here!!
