Bossman - The easy way to remember port and starboard is that port is left, and both words have four letters.
Regarding the rotation of twin engines, the P-38 has unique story to it. When the first prototypes were introduced, the props rotated inwards(such as from the top downward, or, viewed from the pilot, left - clockwise, right - counterclockwise). The resultant propwash outboard of the engines caused an increase in the "apparent" angle of attack of the wingtips pushing toward a stall. As long as both engines were running, both wings would lift equally, but if an engine went out, the wing on the bad side would suddenly have more apparent lift, and coupled with the immense torque of the good engine would flip the plane on its back in a heartbeat. The P-38 had a very bad initial reputation because of this, but once the engine rotation was reversed, it became a very well behaved and formidable aircraft. for some bizarre reason I happen to know this about the P-38. Probably from years ago when I built the old Monogram kit.
As for other twin engined aircraft, I cannot tell you. But now you've got me thinking about it myself. I'll see what else I can find out.
