Yes, there are still details to be sorted. VLs need specially prepared landing surfaces to resist heat and velocity related damage, spalling etc. It's unlikely that Miramar has installed these yet - at least in airshow areas.
All F-35s (with a few exceptions) are still limited by restrictions put in place to avoid "blade rubbing," presumably until the root cause is officially identified, and I suppose a retrofit is designed, tested and installed. Perhaps a "break-in" routine could mitigate the situation in the interim.
Finally, the F-35B has modifications that need to be performed before IOC. Some of these involve door hinges and replacing/doubling structural frames that will take some time to retrofit.
