Change "ifdown eth0" to "allowhotplug eth0" that way it'll just bypass it if 
no wire is plugged in, but it'll work fine if one is.
Of course under the allow line add:
iface eth0 inet dhcp

To answer the other question, no you do not have to disable one to use the 
other, as a matter of fact you can have them both running at the same time.
And, if you want to completely disable eth0 black list the module, or take any 
line referencing eth0 out of the interfaces file.
