All the books are in the link below. The first PDF on the list is the Traveller Main Rulebook, and has all you need to make a character. Anything named "Book #" is a supplement with more stuff for characters (except Book 0, which is just an intro book). Additionally, the Central Supply Catalogue (Supplement 4, second tab) is good for spending your money.

You start off your first term at 16 years old (not 18 like in the book). This gives you one extra term before you have to roll aging penalties. Addtionally, you get to use up to 5000 of your credits to buy your equipment (instead of 1000 credits).
