Depending on how much time you have, try setting up a stage with several targets at different distances (5-15 yards) and work on your front sight flash/double-taps. Make accuracy/efficiency higher on the priority than speed - speed will come with time/practice. If live shooting practice is not available, set up some mock up stages at home and do walk throughs with your pistol.
And yes, smooth is fast.
Look at some YouTube videos to get match/staging ideas. Learn from masters (Rob Leatham, Todd Jarrett and others) and duplicate what works from the beginning and don't reinvent the wheel.

I found that new shooters (and seasoned shooters too) benefit from video taping the shoot of your performance and reviewing later to point out areas of improvement - stance/posture, grip quality, sight alignment to head/front sight flash time, efficiency of mag change, smooth movement between targets (your head/sights should move as a unit), etc. - same as football team reviewing tapes.
Have fun and keep an open mind to soak up from other seasoned shooters (their coaching may be invaluable because they can see what you are doing wrong and point out how to improve your performance).
