So if i flash it the way arco suggests (with ODIN) i don't need to root it first, and i just follow up his instructions?
just follow it.. but I recommend using "Terminal Emulator" that doesn't need PC.. but needs root.. -same way to flashing by adb shell-
THESE STEPS NEEDS ROOT & BUSYBOX, DOESN'T NEED PC & ODIN..
FOR BEST RESULT, UPDATE YOUR SUPERUSER.APK, SU BINARY, AND BUSYBOX

-download and extract it..
-put the recovery.img in /mnt/sdcard
-download "Terminal Emulator" by Jack in market (FREE OF COURSE)
-open it then type "su" and click enter
-allow root access..
-then type "dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p13" then click enter <~ THAT IS "0" (ZERO) not "O" word..
-then some text will show in bottom
-exit terminal.. check the recovery by turning off the device then turn on with volume up botton, home button, and power button pressed together.. until "Galaxy W" screen shows up, release the power button only.. then you will enter CWM
-navigate with up (up) n down (down) vol button and home keys (select) and power (back) and click "reboot system now" to reboot
HAPPY FLASHING

it can be done in any ROM.. handy right..
Note: the input file (if=/)depends where you put the recovery.img
