Paulo is mostly right about the meanings, but I can explain a bit more about the second one.
 * "I'm not so much holding my breath."

Firstly, you should know that Reed Wahl phrased this oddly because his character is not a native English speaker. A more common way to phrase it is "I won't hold my breath." Basically, to "hold your breath" means you are excited about something that you think is going to happen soon. Thus, saying "I won't hold my breath" is a sarcastic way of saying you don't expect that thing to happen.

Wahl is basically saying that he doesn't expect the outcome to change from what the machine has foretold.
