Chances are they will not jump, UNLESS you stress/ provoke them.
I'd suggest turning off the lights for atleast 12-24 hrs., or you may shock them.
Also, acclimating for over 3 hrs. is too long IMO. You shouldn't have left the floating in the bag that long due to oxygen depletion, but they should be fine.
And as everyone else suggested, do either glass tops or egg crate. Either will work.
