Magli: I think that the smuggler's contacts are with the Republic as opposed to the Empire. It's a moral choice that depends on the heart of the smuggler. It's basically the Han Solo model; no matter how gruff you are, this is the cause you decide to support when push comes to shove. I think the first reason is enough to fall back on for the dark side smugglers; it all comes down to how the smuggler is affected. The smuggler's ship is lost to separatists who are against the Republic, so therefore, the smuggler allies with the Republic.
Cow: In the beginning, it's really disappointing to see that all of the race choices are humanoid, but then when you actually play, you see why BioWare sacrificed those options in favor of allowing extra customization. (Trust me, cause I thought the exact same thing you did!
