While on Tatooine, you will go into the cave of the krayt dragon after it is dead to retreive the star map. When you come out you will fight Calo Nord and a band of mercinary scum. You should do the Krayt Dragon mission first as later on in the game Calo is extremely tough to beat if you don't beat him during this mission.

You can easily gain two Krayt Dragon Pearls simply by following the Dark Side. After killing the Krayt Dragon on Tatooine, demand more money for the task (from the Twi'lek who conceived the mission). When he refuses to give in, kill him and loot his body for a pearl. A second pearl should be in the Krayt Dragon. Both should upgrade your lightsaber considerably.

When your character gets to Korriban, head to the Sith academy, outside the tombs (where the archeologists are) and be sure to take Juhani with you. There is a character off to the left in the Valley of the Dark Lords named Dak Vesser.

Ask him who he is and Juhani will recognize him as a lost Jedi lover. Dak is bitter and will leave and be in the cantina. Go there and talk with him WITHOUT Juhani. You will be able to tell him that you are going to kill him and you will fight. After you kill him, collect his remains, including 150 credits and a lightsaber crystal.

Now go out of the cantina and take a left to the valley where the entrance to the Sith Academy is, and turn right back around and go into the cantina again. Dak should be alive (as long as Juhani is not with you), so you can talk to him and kill him over and over again! The lightsaber crystals you get from Dak are worth nearly 2000 credits each on Yavin 4. You also receive a lot of Dark Side points if you opt to do this.
