To expand on what Hot Space said, one major concern other than the bounce on landing was forward visibility in the birdcage Corsairs. The Brits got around this by having the Corsairs come in for landing from the side of the carrier and they only straightened out to land at the last moment so they had better visibility on their approach. Also, the FAA carriers hangar decks were slightly lower than the American's, so eight inches was cut off each wing tip (clipped wings). Inadvertantly this also reduced the bounce on landing somewhat.
I'm not 100% sure, but I'm pretty sure that vast majority of the design changes to the Corsair to make it better suited to carrier ops was by VF-17 Jolly Rogers and a Vought representative. They flew and were carrier-qualified in F4U-1 (birdcage) Corsairs. VF-17 and the representative came up with the small spoiler on the right (I think) wing so that the left wing wouldn't drop suddenly at low airspeeds (ie carrier landings), the first bomb racks for Corsairs if I'm not mistaken, an improved tailhook, and I think there were some other minor changes. VF-17 was ripping off tailhooks on carrier landings when the hooks got caught on the deck and when the hook broke it flew over the stern of the carrier, and in the ensuing wreckage no one realized the hook wasn't there. The reason it was realized that the tailhook was being torn off the Corsairs was that a greenshirt - who I think were the ones to get the wire off the tailhook - saw the hook going flying over the stern.
