It was not shown that the lawyer talked to Emily until the pier scene. The lawyer was told by Victoria that she had other people to call to do inside jobs for her. After the pier scene, I just concluded the lawyer told Emily right away since she rushed to get the tapes there and hid them in a really bad spot if she was just setting Amanda up to take the fall eventually.
Interesting thought that Declan finds the tape and tells Charlotte.
I think she cares for Daniel to the extent she knows he's not guilty of anything, is just a pawn in her game, howver she has gotten comfortable with and may even be enjoying a friends with benefits relationship with him (that he thinks is love). But the romantic in me says that her heart belongs to Jack.
