First off, welcome to the party. In which cities/games are your tickets? You can see who is else is going from the forum on this running thread: http://www.rooshvforum.network/thread-8879.html
Second off, and you may have already known this, but Brazil is giving out special tourist visas for FREE (normally $100+ for US citizens) with proof of World Cup tickets. I believe it grants you a 90 day stay, but here are the details: http://chicago.itamaraty.gov.br/en-us/visas.xml
My nearest consulate was a 7 hour drive and I made a weekend out of it - I prefer to handle that kind of thing in person. If you still want to mail it, get going on it now, it could take up to a month of processing.
As far as courier/expediting services, other members will have to chime in...
