The game is just like vim/emacs in that you don't know what you don't know and you're likely going to learn piecemeal.
If you looked through a couple tutorials and said "Hey I think I get the hang of it now" and start cracking at your first mountain, you'll quickly realize that you have no idea how to craft, deal with rooms, plant stuff, etc.
As far as the graphical elements of the interface goes, there's a number of tilesets to use[1] which make the game exponentially more enjoyable.
Also, there's a fellow on YouTube by the name of captnduck[2] and, aside from the official wiki, he's probably been the most helpful source for me when it comes to DF. I suggest taking a look at a video or two from him if DF interests you.
