Presumably, the court will determine the pending motions. The court may defer decision on your discovery motion to give your wife time to find a new attorney.
Some courts routinely schedule hearings on motions. Some only schedule hearings when they think it is needed. We have no way of knowing how the unknown judge handling your case does things.
First of all, when you ask your attorney something and his answer isn't clear, ask that he make it clear and keep asking until you understand. That's one of the biggest parts of an attorney's job. Second, if you don't want to pay your attorney to do his job, why do you have one?
Determining how long it "usually takes" for a judge to decide a particular type of motion obviously requires familiarity with that judge. Even if you had identified the judge (and you shouldn't) and the county where your case is pending, the chance that someone familiar with the judge will happen upon your post are virtually non-existent.
This is why you have a lawyer.
