As was told to me, probably by either moot or kilo, there is a certain trick to getting out of those pesky flat spins. "When" you stall out into a spin: 1) chop throttle, 2) push the stick forward, and 3) apply the rudder opposite to the direction you are spinning. Though you will lose a lot of alt, you will eventually build speed and counter that see-sawing leaf rock.
As for the attack, speed is paramount. Make slashing attacks from the high front quarter of the bombers. Dont slide in behind the tail defenses. Like it has been said, the 152 has a glass jaw. Dont make radical control movements, or you'll drop out like a rock. I like the 152 for high alt chases, but i usually defer to the 190 A5 if i can set up ahead of the attack given the greater armament and armor.
The landing is particularly trick too. You'll need to use your flaps big time at low speed. Be smooth and graceful in your movements, dont over correct or jerk. Try not to use the rudder too much or you'll do a 180 on the runway resulting in complete destruction.
