im just starting and wondering which one is the best?

Seen a lot of Storms end game clear everything without trying.

chose storm
edit: do I need to assign my skill points correctly. is there a way to screw up?

Scarlet Witch is another good choice. (Her and storm have the AOE thing for clearing mobs endgame)

Daredevil is fun after level 10.

Hawkeye is good for pvp (highest single target dps)

Thing is.......

do I need to assign my skill points into some certain skill or can I scatter them everywhere?

Think Diablo 2.

You want to focus on a move or two to be your "main."

Don't put too much thought into it and stress yourself out, Retcon devices can be purchased (with irl money) or found in-game. (I think you even get 1 as a quest reward.) And Retcon devices allow you to re-spec your skills.

do u know which one is best? skybreaker,windrider, stormcrafter?

It's all preference, play whichever you like the most.

windrider is my favorite, what do u think of that compared to others?

It's slightly weaker because it has less attacks. But it's definitely a tree all Storms use (for flying / sorocco rush etc)
