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.
SCT Controller described a conflict event between a LGB Air Carrier arrival and a VFR King Air departing SNA seeking an IFR clearance; the reporter indicting a heads-up from SNA Tower would have eased the situation.
