What the *@#!... ATC?!

Flight from Buchanan Field (KCCR) to Santa Ana (KSNA) using Eaglesoft's BeechJet 400A and shot the ILS for 19R, even touched down on the numbers. I clear the active, request clearance to parking which was given... was told to hold short for a KingAir on final (had to cross active), which I did... was told to continue taxi, when I got ran over by Southwest 737 taking off!!!
