Even if Quirrell weren’t responsible, he would almost certainly have the presence of mind to quickly check whether any high-value targets (Harry, Hermione, and possibly Neville) were missing. Harry manages to do the same, albeit after some unwarranted delay; he would not expect Quirrell to forget it.
Maybe. Harry didn’t remember to check until after Quirrel had left. I think it wouldn’t be hard for Quirrel to convince Harry that as soon as he realized Hermione was in danger he came as fast as he could, especially since he really DID burn holes through Hogwarts to get there. He will need a believable explanation of how he knew where to go, though.
