I think C3PO will at least have his memory wiped since he can't keep his mouth shut. R2D2 might as well, but I think maybe not. He can't talk normally but I get the impression he is much more in the know than C3PO. He knows all this stuff but keeps his mouth shut. As for Han shooting first, of course he did. Han didn't become a succesful smuggler by sticking to the rules. Greedo said he was going to either kill Han or take him to Jabba (who isn't exactly happy with him) so Han does whats necessary. If he had known Greedo would be the one to find him he would have hidden in the shadows and shot Greedo in the back when he wasn't looking. You can be the loveable rogue without being a goody two shoes
