I got the following information at 
http://www.swg-de.com) and here it is... 
 Professions in Star Wars Galaxies are handled differently than any other MMORPG before it. There will be a total of 27 separate, titled professions ready for launch, with new ones being created and discovered by devs and players alike. 
 A profession is basically a collection of skills that you've learned. If you learn the correct skills to cut hair, then you will have earned the Hairdresser profession (yes, that's a real profession in the game). Certain simple professions can be started during the character creation screen. This is basically more or less a starting template for your character, with the six or seven skills that fit with the profile of someone in that profession. 
 Starting out in a profession doesn't mean that your character is stuck in that role for the rest of his existence. You can choose to 'lose' skills so that you can learn something new, starting a new career. Anytime you have the required skills for a main profession, your character gets a title, like Bounty Hunter for example. You can pick up multiple titles in other professions by learning the prerequisite skills. You will also have the option of revealing some or all of your titles to other players in-game, which is handy for when you want to sell your skills. 
 Related skills in SWG are grouped together into "disciplines". Disciplines range from Linguistics (all language-based skills) to Evasion Tactics (skills that help you avoid damage in combat). Even further, disciplines are grouped together into three "discipline categories". There are: Social Disciplines (Linguistics, Dancing, etc.), Commercial Disciplines (all the crafting disciplines, farming, etc.) and Adventure Disciplines (basically anything dealing with combat and exploration). A profession might draw upon skills from several disciplines. 
 Likewise, a "profession category" is, like the discipline category. In fact, the categories have the same names: Adventure, Commercial, and Social. All professions have at least one combat-related skill, regardless of their category (I wonder what combat skill a hairdresser requires?). 
 An "elite profession" is a profession that becomes available through exploration of the other professions and disciplines. At launch, there will only be a handful of elite professions, like bounty hunter. 
 In all, there will be:  
 27 professions 
 41 disciplines 
 Over 450 skill boxes (not including titles) 
 The devs promise that the profession/discipline/skill system is so flexible that it can only continue to grow. 
 The following is a list of professions that have been announced by the devs:  
 Bounty Hunter
