Taxy Instruction Issue and Descent too soon?

I was flying out of KPHX to KSJC in the PMDG 737-800 last night. I was parked at Gate 4 and was told to expect runway 08. When I received taxi instructions in addition to the expected C C4 B and B13 it included to hold short of runway 07L. This is on the other side of the airport so there is no way I would be anywhere near there. I have run the latest makerwys.exe. Both airports are the stock standard MSFS sceneries. This was the second time this has happened here.

The rest of the flight went well until descending on the STAR SILCN6 with KLIDE transition. At TOD I requested FL290 but was told to descend to FL300 which was fine. I was cleared for the descent via the STAR. Then shortly after I was told to descend to 4000ft to KLIDE. This was way too early to descend over that terrain so I descended as per the chart. From KLIDE the track intersects with the extended centreline for rwy 30L but I received no further comms from ATC. I tried reporting on both CENTER and TWR that I was established on the ILS for 30L but no replies. I landed OK and cleared the runway. Did my after landing checks and then received a CLEARED for ILS 30L. Not too sure what I could do at that point so I taxied to the gate and shutdown. Any ideas how to sort this out. I did look at Taxy Maintenance but it was just heaps of green icons between my gate and the runway.
