However, on my NAT'd VirtualBox Ubuntu, there is no wlan0, only eth1. This gives an IP of 10.0.2.15 which is obviously not the IP assigned by my ISP.

point 1 makes sense. it's not bullet proof. but, unless you are dealing
with malware that is designed to break out of the restrictions imposed
by a vm, you have spared yourself a headache. you can further mitigate
against such common malware risks by using a system of snapshots. while
not as ideal as a "live" configuration, after you set up your virtual
machine for use, you can make a snapshot of it and, after each completed
session, restore your vm from the snapshot. unless you received malware
designed to exploit a vm, this will result in the malware being gone the
next time you use the vm as well.

point 2 does not work.  any malware that phones home will show your ip
address in that configuration.  however, if you use something like
whonix, where you have a gateway vm that pushes all of your workstation
vm traffic through tor, you have another layer of protection against
malware with phone home capabilities.
