Your motion, if you did it right, should be set on a particular date and time. The defense's motion to dismiss should also be set on a particular day and time. I agree with my semi-anonymous colleague that you're in way over your head if you don't even know what these documents are for and when these motions are set to be heard - that also means you don't know when oppositions and replies are due.
Beyond the procedural gaps in your knowledge, if you think any lawyer on Avvo can advise you how to oppose a motion to dismiss without knowing a thing about your case and that particular motion, I'm afraid you don't even know how much you don't know.
Do yourself a favor and get yourself a lawyer before your case is dismissed. Judges often cut pro se litigants a little slack, but not a lot.
