Honestly, I think the easiest method would be to install an ssh server on the tablet, then use an sftp client on the PC/MAC/Linux machine. I personally use Filezilla. Get the IP address of your tablet, and plug that information into filezilla. (To find this open the Connection manager and select Internet connection > IP address from the menu.) You will also need the root password, which you should set up when installing ssh.
Then, it's just a matter of navigating to the 2 directories and copying the files over. You can also chmod (change permissions) right from filezilla by right clicking on the files once they are copied over.

I don't think it really matters if you copy getpass.py to /usr/lib/python2.5/site-packages or /usr/lib/python2.5. I think python probably looks at both folders internally for any dependencies it needs.
