Default [Q] roms for gs2 sghi757 and cwm recovery problems

i really want to get pacman rom for my samsung galaxy s2 sgh i757 (bell version) but i can't find the file of the rom to download... the closest version i could find is for the i777. is it okay if i flash that onto my phone? or will it magically turn my phone to a paperweight. and also my samsung can never get into recovery mode. EVER. even if i use a app to reboot into recovery. and i'm pretty sure i did everything correct except for the fact that i think i need to update but rom manager says my device isn't supported. thanks for helping out a newb! help much appreciated.
