"erase nvram" and "erase startup-config"

Now I know that these two commands do the same thing. However, are they the only commands to type to get a router back to its default configuration?

What about VLAN information? Should I erase that with "delete flash:vlan.dat"?

yes vlan information is deleted by delete vlan.dat (this is for a basic switch at least.)

I normally do write erase to remove config.
