One TLC277 has to OPAMPS inside. So you just have to order 5.

Hm. I think it has to be 68k (same as this resistor in the other channel)

2.54mm, I think. These are the ones commonly used for eg the IDE harddisks
and floppy drives.
2 rows connected with 3/17 pins.

Nothing. A virtual part.

They are small silver nail-like things. You can solder them into the board
and later connect the power supply cable to it. But you can also
solder the power cable directly into the board.
