Your mystery part looks like a coil.
As for tube socket identification, this is simple.
Look at your sockets. You will see that there are two larger pins on most of them. Picture these larger pins as being on the bottom looking at the socket. As you do this, start from the left hand one of these larger pins, this is Pin 1. Each pin going clockwise from there is pin 2, 3, 4, etc.
The exception to this is the 5 pin tubes. If you look at those, you'll see they are in a sort of pattern like a baseball base, with pin 3 being the pointy end of the base. Counting counterclockwise from this, you have pin 2 and pin 1. Counting clockwise from there, you get pin 4 and pin 5.
