"Following that second test flight, the U.S. Federal Aviation Administration (FAA) identified 17 corrective actions for SpaceX to take before the next flight: 10 on Starship and seven on the Super Heavy booster."
Sorry, this is incorrect. SpaceX, not the FAA identified the 17 corrective actions and submitted them TO the FAA for review. The FAA then just last week approved the corrective actions.
This is good because since SpaceX identified the corrective actions, they have been working on them since the 2nd launch last November. That's why they are now ready to launch again pending an actual launch permit from the FAA, which sounds like it should be very soon based on the announced tentative launch date!
Regarding Jan Wolitzky's question, yes, again the plan is for the booster to be dropped into the Gulf and Starship will complete 1 orbit and then be dropped into the sea just off of Hawaii. At this point in the tests they might attempt to hover each just above the surface of the ocean to simulate actual landings.
They have the next 2 boosters and Starships nearly complete so the hope is the subsequent tests will increase in cadence.
Edit: It has been reported the FAA is very close indeed to approving the modified launch license for this 3rd flight.
Regarding the objectives for this 3rd flight, this is a post from SpaceX:
The third flight test aims to build on what we’ve learned from previous flights while attempting a number of ambitious objectives, including the successful ascent burn of both stages, opening and closing Starship’s payload door, a propellant transfer demonstration during the upper stage’s coast phase, the first ever re-light of a Raptor engine while in space, and a controlled reentry of Starship. It will also fly a new trajectory, with Starship targeted to splashdown in the Indian Ocean. This new flight path enables us to attempt new techniques like in-space engine burns while maximizing public safety.
Exciting times!
