1. I agree with you.

2. Law warped DD once more before, and to the rougly same location (when the building was cut) maybe (just speculating) for long range teleportation Law has to mark the place somehow and since the marked place was Dressrossa he got there once again.

3. Devil fruit users do also carry weapons at times, look at BB,he used a gun against WB. A gun is easy to use and effective at times. Also DD could have had the gun hidden in his pocket. Maybe he exhausted some of his string powers fighting Law and as the Strawhats are around he is preserving them, so decided not to use the DF power to kill as a gun could do the same. Or he was perhaps using his invisible strings to pin Law down to the ground and thus could not use them to deliver the final blow and thus used a gun instead.

4. Could be but could also have some twist.

5. No clue.
