Editing the bots name is simple, as one of the steps tells you to create a member on your forum, which will act as the bot
As for the other parts, log into your phpmyadmin and collapse the database on the far left, you should see a list of the tables inside and i believe one is called "bots" or something like that. I cannot be 100% because i do not have this installed. You may find more information and help in the TomBot's thread.
Sorry i couldnt help any further
