There are no pre-configured commands for Vera, so yes, you'll have to create them yourself.
And since people tend to have different devices and scenes anyhow, it wouldn't necessarily make sense.
Hopefully there's enough documentation available that it will be fun rather than overwhelming, but let us know if you run into obstacles you can't overcome.
See
http://voxcommando.com/mediawiki/index.php?title=Plugin_VeraThere are also video tutorials on editing/creating your own commands. (See "Editing Commands" in the wiki for links to the videos and more info.)
Here is one example Vera command that you could dissect to get a sense of things. Note that in our house, device ID 51 is my bedroom fan. Scene 1 is a Vera scene that gradually turns off all the lights in the house as we get ready for bed.

<phrase>Good night Acer, Sweet dreams, Time for bed</phrase>
</command>
