I would recommend doing this on the 4th mission, Empirical, as it is the shortest mission in the game. For the first objective, destroying the escape pods, all the escape pods will be located on the left in the third big room you come to. Simply force lightning all of them; they will lurch forward and eventually explode. For the second objective, force points, just try to vary your attacks and limit the use of your lightsaber. There are only 5 holocrons to find, which you can find here:

Holocron 1 -- In plain sight upon leaving your convalescent chamber.
Holocron 2 -- In the large room with test tubes, check the enemy spawn
directly under where you entered this zone.
Holocron 3 -- In the large room with test tubes, break the test tube and shiny
holocron get!
Holocron 4 -- Escape pod room. Move or destroy one of the lifepods near the
zone exit to see the holocron.
Holocron 5 -- After the scape pod room, but before you attack the Purge
Trooper, check all the cargo boxes in the hallway.
Also, the achievement will not unlock until after you have finished the mission.
