Getting ready to flash w580

Ok. So I've been doing some browsing and I feel like I'm just about ready to flash my phone. From what I've learned, this is the process I am supposed to follow...

Flash Filesystem, Main, and Customize Phone (select appropriate custpack from list, or add one to own_custpack directory in XS++ folder) Then hit Flash... you CAN do all this in one flash session, but this method takes longer (5-7 hrs) because it must bruteforce hack the phone to upload the custpack.
(taken from Can Someone Pleeeeeeeeease Help Me with W580 Custom Packs? - SE-NSE Forums)

I am in the US using Cingular (sadly, now AT&T). I downloaded these three files. I am not 100% sure if they are what I think they are (meaning the Main, FS, and Custom).
1)HB1_06_Gen_CDA102568_106_R8A_GENERIC_AMERICA_1.z ip Main (this IS the main, right?).
2)W580_CXC1123362_GENERIC_LA_R6BC002_RED52_MAIN XS.rar.
3)W580_CXC1123364_EUROPE_2_R6BC002_RED52_fs_XS.rar .

I believe the first two are mains and the last one is fs. I believe all I am missing is the custom pack (meaning the America 1 pack). Can anyone tell me if I'm on the right track? Also, is there a chance someone could get that file for me? I'm not quite at the required number of posts yet. Thank you very much.

Whoops. After looking at it again, I think the first file (generic america 1) is the custom file.

Oh also, I forgot to ask, does it matter that the FS says "Europe"? Is there a file for people in the US? Or does this simply structure the phone and so it doesn't matter where I am?

I always thought of it as the language.. like with HK firmware Id expect chinese and english (which it does)
With euro it should still have english... which is what you need im guessing

Ok, so I'm pretty much ready to flash. I was actually about to flash right now, but I can't figure out how to get the custom files to work.

I think I have them, but I'm not sure if they're flash files.

Why did they have to lock these damn phones?

This really sucks!
