Welcome to the Elite Galaxy commander!
I'm one of those players having many thousands of hours in the game (currently approx. 7,500) . So, obviously, the grind doesn't bother me. However, in Elite you can can grind smarter instead of harder. The info listed below can help. Remember: the fun is in the journey not the destination. In fact there is no destination.
Maybe you've found most of the resources listed below already. If not, have a look at them and in any case don't hesitate to ask questions here in the forum.
In-game help is available in the form of menu links to the Pilot's Handbook and the Codex (right-hand cockpit panel 1st tab).
For a very good beginner's guide see:
An in-depth beginner’s guide to Elite: Dangerous.
Tutorials covering all aspects of the game, many of them in the form of YouTube videos, are available from
ED Tutorials.
There is a wealth of useful information available in these forums spread out over hundreds of threads. Thanks to commander
