Objectives: Steal the Ebon Hawk
After you get squared away in Davik's guest quarters, you should start abusing his hospitality in the most nefarious ways possible. Killing every single person you meet might be a good place to start, whether you're Light side or Dark side; after all, this guy's a crime lord, so his guests aren't exactly going to be upstanding citizens. If you're a Light side trainee, then you may want to not instigate fights flat-out, but don't worry, there are plenty of guards to mow down.
First, though, outfit Canderous with whatever equipment you can spare. He possesses a truly massive blaster, which should suit him fine as a weapon for the time being, and an innate ability to slowly regenerate damage, which makes him an ideal candidate to take the lead when going through doors.
As per usual, explore the area as you see fit; there is quite a lot of treasure hidden away in footlockers throughout Davik's mansion, though some of it is behind locked doors. Proceed in a northwesterly fashion until you come across a bounty hunter roaming the halls. Exterminate him, and pick up the computer passcard from his remains. Proceed northeast from here, into what is winkingly called the "Guest" Room, where the Ebon Hawk's former pilot is being held in a torture cell. Unfortunately, he's guarded by two massively powerful droids who can use stun beams and flamethrowers from across the room. Use ion rifles and ion grenades to take them out, then free the pilot using the control panel. He'll give you the access codes to the Ebon Hawk. Dark side players can murder him afterward to earn some points. Now, continue your sweep of the compound until you find one of the security panels. Use the access card you found to disable the hangar security in the command menu.
You should be able to see the hangar on your map, from the tour, so proceed to the southwest until you find the door. Heal up your party before entering the hangar, and make sure you don't have any areas of the estate that you still want to explore. If Bastila's along, you may want to let her rejuvenate her Force points; just let the game sit unpaused for a few moments, then save your game.
Once you pop into the bay, Davik and Calo appear and start to rather energetically defend their right to take off with the Ebon Hawk. They're both tough, but concentrate your fire on Calo; Davik has a much higher defense (27) than does Calo (19). After you knock Calo's vitality down enough, he'll threaten to blow everyone up with a thermal detonator. Unfortunately, the Sith bombardment throws a kink into his plans. Grab what you can from Davik's body, board the Ebon Hawk, and leave this hellhole behind.
Unfortunately, even the correct launch codes won't protect you from the Sith starfighters that are intent on shooting down the Hawk, so you'll have to jump into the gunner's seat and use your quad-laser cannons to blow some Sith out of the sky. Use the analog stick to aim, and the A button to fire; don't worry about speed here, or, for that matter, during any other of these turret mini-games; the Ebon Hawk seems to have more than enough shielding to handle the fighters. One thing you can do to shorten the fight is to rapidly press the fire button (A) right as the mini-game starts up; most of the fighters will be flying straight and low overhead during this time, so you'll have a good chance of taking down two or three of them immediately.
