Which version of GApps for CM10.1 (Owl Project)? topic

So I'm looking for the correct version of GApps for CM10.1 (Owl Project). Their page doesn't say anything about installing GApps. Also, will I need to increase internal storage to be able to install GApps?

eg) Using something like INT2EXT? Is there anyway to do that without having a SD card reader, could I just plug my phone with the SD card in it to my PC?

Thanks :)
