Frankly I'd just wade in, introduce yourself, say that you are new to the game and see how it goes.
The first few hours of the game are the hardest, do feel free to ask as many questions in the forum as you wish, no one is born knowing this stuff and we all had to start from scratch at one point.
My advice to anyone starting out is to start small, it's easy to get caught up in the threads that talk about big trade or combat payouts, but those come with time, I remember my first few hours was doing things like hauling biowaste or food, work on getting some money even if its not glamourous or exciting, then concentrate on upgrading your ship modules, don't worry about changing ship too soon, get what you have to at least C grade with an A grade FSD.
When you've got a decent buffer of money upgrade the other modules, but don't over do it until you have a sufficient power plant.
When you do come to upgrade to another ship, remember the single most important rule - "don't fly what you can't afford to insure".
And remember, there is no shame in running away, any good Commander knows that it's better to live to fight another day.
ED takes time, there is no short route (although some are faster than others), take your time, enjoy the ride and before you know it you'll be deciding whether you should be buying a Conda, Vette or Cutter
Ask lots of questions, there are no stupid questions, and everyone is always happy to offer advice.
But most of all have fun, oh, and Fly Safe o7
