The Landing Platform
...pretty self-explanatory.
The Dining Room
The door to the Dining Room slides up (by rotating the white spiral piece on
the left), allowing our heroes to enjoy Darth Vader's hospitality. Don't forget
to place Vader at the head of the table!
The Carbon-Freezing Chamber
(the best part!)
"I know", says Han...
There
is a wheel piece behind Han ~ spin it, and down he goes into the chamber.
Slide Han to the right by pushing
the Han carbonite block from the left 
(hidden
by the support beam).
Once the switch is made, turn the wheel again and up comes Han in carbonite and into the waiting hands of the (newly-decorated) Boba Fett.
The Luke/Darth Vader Battle
Luke and Vader duel it out, using anything and everything as weapons, even the walls:
A little touch on the tan 1x2 handled plate releases the wall section.
Then, Luke can fly out the window:
(This is a rear-view of the wall/window). There is a lever for popping open
the window ~ set Luke on the ledge of the window, snap the lever, and Luke will
fly out.
Vader follows for the final confrontation...
...and
devastating revelation.
And finally....another closeup of the Lando minifig:
