Do kernel modules need to be aware that they are running in a 64-bit kernel or a 32-bit kernel?
Yes, if they want to support 32bit programs in a 64bit kernel they usually need ioctl translation and sometimes syscall translation (if they have own ioctls or syscalls)

How should be the modules be written so they work both on 32/64-bit kernel AND can interact with both 32/64-bit userspace programs in a 64-bit kernel??
