Besides the P-38, there aren't many other planes that are as written about on these forums as much as the F4U's. Just run a search with a few tag words in it such as Corsair and you'll come up with tons of great info.
One thing you'll notice in your studies, however, is the amount of information that seems completely contradictory. Saxman and I, for example, have (judging by our posts), very different styles of flying and fighting in Corsairs, yet each of us have fun and success with them.
Don't be put off by the "conflicting" advice... It merely is a good sign that the Corsairs afford you a number of different options. You can keep them fast, bring them slow, fight from high or on the deck. She's one of those rare birds that really is at home in all types of situations, whether that be as a TnB, BnZ, or E fighting style.
If you really want to improve in it from a TnB perspective, my advice is to grab a bunch of squaddies, go to the DA with them, split into two fields, and tell everyone to pick their favorite plane. Then practice turnfighting Zekes, Spits, Hurricanes, FM2s, 109s, etc.
In other words, do everything many people say can't/shouldn't be done. You'll hear people say, "Against a pilot who knows what they're doing..." Many times. Don't worry about that
there aren't many people who fit that bill in the MA.
