Skill points beyond 20

Is there a cap to how many skill points you can earn onc your level maxes and exp then begins earning SP? On a related note, what is the cap for your attributes?

If there is a limit on skill points, I doubt anyone has found it yet. I have a couple characters with well over 300 skill points.

200 is the max attribute points per character. 170 at level 20 and two quests that give 15 each as a reward.

I don't think anyone went close to a skill point cap if there is one... I currently have around 400 on my pve monk, and I guess that if there was a cap it would be at 999.... Don't think anyone will ever reach it to prove it though

Makosi has 15mill exp+, with 1100 skill points earned. There isn't a cap at 999, so probably isn't one at all.
