Technical traffic ticket question(Washington state)?

okay, so in July 2010, I got a negligent driving ticket for speeding and I took it to court and it was eventually deferred in late August. The deferral means that I can't so much as get a traffic infraction within 12 months of the date of deferral (late august 2010). However, today (5/13/2011), yes thats friday the 13th, I got an infraction for going 60 in a 45. So basically in my view im totally screwed: $144 dollar ticket plus the deferred ticket comes back right? So were looking at a $700 ticket. Now my question is, if i mitigate this ticket and ask for the court date to be pushed back until september, will the deferral from august 2010 still be valid? Will the infraction be set by the court day that it is settled or the day the cop gave it to me? Also, is it possible to pay off a ticket with community service work?
