debranding w880i

hi all
I just got my new w880i and its great, only thing that bothers me is the oprator logo etc...
Im going through loads of info on this forum and some other as well so I think Im ready to go with the operation ;)
I just cant afford to destroy the phone so please have a patience with me and help me out.
I got the program to work and as I understood I need the firmware files. Over here I found:
W880_R1KC001_FS_CENT_EUROPE_RED52
W880_R1KG001_FS_CENT_EUROPE_RED52
W880_R6BC002_FS_CENT_EUROPE_RED52
W880_R8BA024_FS_CENT_EUROPE_RED52

Im not sure if this is what Im looking for and should use for flashing, or maybe which of these (what are the differences).
As I said I rather be a noob and ask twice than to ruin my phone.
Thank You in advance for any help.

just in case im posting a picture of the XS++ info
