Yes, the correct total penalty, including "statutory assessments" for neg-2 is $550. The code you cited must be a municipal ordinance, since RCW 46.61.525 is the state law. What city are you in?
As far as a deferral, some courts allow a deferral for neg-2, some don't. You can call the Clerk of the Court listed on the citation and ask if it's a possibility.
And, no, just requesting a mitigation hearing does NOT automatically "take care" of requesting a deferral. You might want to read through this thread before you make any decisions.
Good luck,
Barry
