Apparentely Santa Barbara has returned N740PA to Primaris and has gotten a former Transmeridian plane which is now owned by Pegasus Leasing (the same lessor of the S3 DC-10s).
Santa Barbara applied with the U.S. DOT to fly its own metal to the US back in July. They want to fly two 752s twice daily between CCS and MIA.
The second 757 appears to be from Primaris, a former MX plane and now registered as N741PA.
