With regard to the transporter, it might depend on the type of technology used.
Does the transporter transport matter? In other words, does it disassemble you, transport your molecules to the destination site and then reassemble you there?
Or does it merely transport information? In other words, does it merely send the information about how to reconstruct you to the destination site and then use whatever matter is there to reconstruct you?
The difference might be in whether or not you are still considered you after transport. In the first case, it’s still all you. In the second case, however, it could be argued that the transporter actually kills the person being transported and then creates a duplicate of him/her at the destination site. I’m almost certain that that would have practical differences l’halacha.
As for replicated food, I’m pretty sure it shouldn’t be a problem. Provided that it’s not actually made out of forbidden foodstuffs, it should be no worse (halachically) than imitation shrimp.
