Assuming you've already finished final approach with good angle, flaps, and landing speed and are at the threshold. just what I found works for me:
Cessna's: Start to flare under 30-50ft, throttle a small bit above idle, keep nose at about 8-10 degrees, at td throttle to idle then bake. usually consistently lands at V/S(vertical speed) less than 300 ft/min, even close to 0 ft/min many times.
"Complex" planes with prop control. -see Rod Machado's complex airplane tutorials in Learning Center, also covers short landings, short and tilted runways, fast climbs etc.
737's(and generally similar jets): 100 ft autothrottle disenage if not already. 50ft. autopilot disenage and throttle to idle and begin to flare. 40-30-20ft. raise nose to about 6 degrees, more than 9 degrees will bump the tail end. Landing V/S usualy at -300 to 0 ft/min.
If you're flying a jetliner, PMDG has some good info to download even if you don't have their plane(see "overview of flight techniques" pdf):

Hope it helps.
