You can unzip a gapps package and push the gallery from there to /system/apps/ or something. I think I used the gapps that AOKP is linking.
(ie, adb root, remount, push or use some file explorer)
P.S if you put your phone flat, then rotate it 180 degree's, it'll solve your backspace position issue :P otherwise, beats me..
