OK- with Gary's vote to be applied yet, we are still at just 8...so I was thinking of posting some possibilities for folks possibly on the fence-- despite this being an important carrier battle, there are plenty of other options out there for this one. Other than the USN carriers Yorktown, Hornet, and Enterprise and IJN carriers Akagi, Soryu, Kaga, and Hiryu- there were tons of others ships in the fleets-- light carriers Zuiho and Hoshu; IJN seaplane tenders; IJN battleships including the Yamato; heavy cruisers such as the Vincennes, Astoria, Mikuma, and Mogami; light cruisers like the Atlanta and Nagara; destroyers like the Hammann, submarines, oilers, and minesweepers.
Aircraft-- USN included Wildcat and Buffalo fighters, B-17 and B-26 land-based bombers, PBY-5A patrol planes, Devastator and Avenger torpedo bombers, and Vindicator and Dauntless dive bombers. IJN planes included Zero fighters; Rufe, Jake, and Dave floatplanes, Kate torpedo bombers, and Val dive bombers.
I am finding it difficult to find out much on what sorts of land-based vehicles or guns the Japanese had as part of the invasion fleet, but I would assume there would be some sort of support vehicles. I will keep looking...and will post pics this weekend as well.
