When editting the title, all you have to do is go to the edit screen and look at the article's title. There should be an image of a pencil to the right of the title, which if you press will allow you to edit the title. I've editted the titles of my own blogs without needing to make a new one; if you ever need help, consult someone's help before making assumptions that nothing else can be done.

As for deleting blogs, that has to be done through a moderator (ie. someone who has editting powers that goes beyond what normal anons/users have access to). But, in most cases, you should only delete a page if that page violates the rules or policies of the wikia; deleting one to make a similar blog doesn't (or should I say "shouldn't") pass as a reason. The old page could have had precious comments or edits that will be lost because of the deletion; if you are new to the wikia, always ask for help when you are in a rut.
