Is it possible for a rogue to get a second action/bonus action?

I know all characters get one action and one bonus action, but say I want to use misty step (As an Eladrin) and follow through with my dual swords. I know that Misty Step is a bonus action, Attack 1 is an action, and Attack 2 is a bonus action (I think). I also know that you can move up to 5 feet as a free (non-normal/bonus) action. At higher levels are there any feats, or are there any magical items that give you another action or another bonus action?
