Ok can I do this???

Turn 1 Assign a focus token to my ship as my action. Use expiermental interface to use Landon abilities then get a stress token.

Turn 2 do a green manuever, remove stress token and then do the above again???

Seems too good....

Yep, that's right. Lando (crew) is an action so you can use it with EI.

And that's lando Crew - not ship.

yup, Experimental Interface (as well as push the limit) both allow you to take 2 actions in 1 turn at the cost of a stress (the action for PtL just has to be from your action bar, and the action for EI has to be from an upgrade card). Not a bad deal.
