Past Perfect: had + V — действие завершилось до другого момента в прошлом. Past Perfect Continuous: had been + V-ing — действие длилось до этого момента.
«all night» — длительность, причина усталости: had been working.
«already» и момент «when Jim arrived» — действие завершилось раньше: had already left.
Результат: проект не закончен к тому моменту — hadn't finished.
«for ten years» — продолжительный период до переезда: had been living (допустимо и had lived).
