1)Does this approach offer vertical guidance similar to an ILS?
Yes, note LPV in the landing minima.

2)What does LPV stand for? The GPS must be _____ enabled in order to fly it.
Localizer performance, vertical glide path. The GPS must be WAAS-enabled. 

3)What minimum ceiling and visibility should give you the required visual reference to land via the LPV approach, and is an RVR-based approach ban a possibility here?
Ceiling of 300 feet and prevailing visibility of one statute mile. No RVR-based approach ban as this runway is not RVR-equipped.

4)Am I correct in saying that all of the waypoints within this approach are fly-by waypoints? If not, which ones are fly-over?
 By noting the symbology you will see that RW21 and EMKIB are fly-over waypoints. 

5)You arrive at the decision altitude of 1,260 ASL and do not have the required visual reference to land the aircraft. Relative to GPS operations, what action must the pilot take to fly the standard missed approach with GPS guidance?
Pilot must press the OBS button (Garmin products) to gain course guidance for the missed approach procedure. 

6)What action should be taken upon arrival over the clearance limit, EMKIB, if further clearance has not been received?
Hold as published at EMKIB, direct entry at 3,100 ASL.
