Jedi Knight
As you probably already know there are two different factions in swtor. You have the Republic which is the good faction (I.E Luke Skywalker/Obi Wan in the movies) and then you have the Empire, which is the evil faction (I.E Darth Vader/Darth Maul in the movies). Generally the good side pulls in more players in almost every game, but shockingly according to the guild sign up page on swtor's website, the Sith(Empire) currently have a lot more players. We won't know until the game is officially launched of course but I feel many more will go Sith because they resemble "Horde" on WoW.
Regardless of what faction you pick the classes for both are pretty much the same classes just with different names. Just go with whatever race you like the most or whatever you believe in the most as a true Star Wars fan. "May the force guide you." (Corny isn't it?)

Republic Empire
After you've chosen your allegiance you will then be asked Race, Class and what you want the appearance of your character to be. After going through all of these options and completing your character you will be able to play the game. Choose wisely because at this time there is no way to go back and change the appearance of your character! And be sure to read up on the Advanced Classes your character can choose from and their Specializations, make sure you know what you want before you reach level 10.

Quick Start Guides
The Quick Start Guides section is a list of guides I think everyone should read before playing swtor. The guides you find in this section may relate to certain classes or just the general gameplay as a whole. Whichever, I think you should go over all the ones that pertain to you; these include general gameplay guides, guides on your class and guides on the faction you are choosing. If you read each of these guides I can guarantee you that you will be one step ahead come release. While everyone is still trying to figure things out, you will already know them!
Just because I can expect this section to pile up with a lot of guides, here is a brief explanation of how you can easily sort through them. Below is an example of what you will be finding in the Quick Start Guides section.
