Narrative:

An airbus on vectors to the ILS runway 30 approach lgb heading north bound 030. A king air departed sna opposite direction on a local VFR code with sba in his scratch pad. Initial call I ask if he wants flight following to sba? [It] seemed weird to me that he would come off on a local code to sba which is out of sct airspace. He then advised he wanted to pick up his IFR flight plan to sba. I looked over at the departure controller and asked if he would get me his IFR strip to sba. Since there was no prior coordination; as there usually is when they depart IFR; I had no idea what he wanted. I then realized the airbus was approaching the final approach course and turned and descended/cleared him for the ILS approach. The king air was then level at 2;400 ft 2 miles north of the final; I then climbed the king air and told him to expedite his climb for airbus traffic 11 o'clock and 3 miles. While I was instructing the king air to climb; unannounced to me the airbus started a climb in response to a TCAS RA from the king air. The king air; while reading back his climb instructions; advised me that the he had the airbus in sight and that the airbus appeared to be climbing. The airbus then advised that he was responding to a TCAS RA and was climbing. The king air advised that he was turning right in response to the climbing airbus. While this was happening; the towers were opening; the line was ringing from ful and toa tower was calling over the shout line. A heads up would have been nice. It would have saved me coordinating with the king air.
