Yes, the U.S. got a letter 2 days before but ignored it because they were talking peace with Japan. Also right before the attack a radar station at pearl harbor saw the planes coming in and blew it off because they figured it was a group of American planes bringing in Christmas presents and letters for the upcoming holiday.

Second answer.

This is pure speculation.

Yes, warnings were relayed to higher-ups in the military to be on standby. On December 7th early forms of radar picked up the Japanese strike force. This information was relayed to the military authority on Hawaii that brushed it off as a flight of B-17s from the mainland. FDR received a telegram warning of the attack a few hours after the attack.
