Let us know about your case. I am interested on knowing how your case progresses. I have a friend going through the same process. To answer your last question, though late, i am pretty sure you can't apply for advance parole - since they won't allow you back in the country- due to removal proceedings being active. Also, I don't think both cases can be heard on the same case, since the calenders are usually full.
g'luck on the hearings.
