Newbie guide/Classes and races

The first piece of advice that I have to give to newbies would be to try every class. Make a character, play a few quests, see how you like it. If you find one that you like, then look into different variations of that class' play style and tactics, and do research on it so you can make your 'main' character the one you will enjoy the most. To be the best of what you can be, have a plan for yourself. It is YOUR plan not someone elses. Most of the time it'll take you leveling to level 2 or 3 before you start finding your niche.
