Combat with Shadow Jaunt and Shadow Stride

First, can I use Shadow Jaunt with a move action to appear next to an enemy?

Next, can I use a standard action to attack or use a strike maneuver?

Last, can I use Shadow Stride with a swift action to move away?

All in one turn?

Does teleporting away with either the Jaunt or Stride offer an AoO?

Can I use the tumble skill to avoid it?

Would that cause the teleportation distance to halve?
