This is from the Boeing 737 pilots training manual, page 4.48, October 1997
"Fly the nosewheel to the runway smoothly by relaxing aft control pressure. Do not attempt to hold the nosewheel off the runway. Holding the nose up after touchdown for aerodynamic braking is not an effective braking technique."
"To avoid the risk of tailstrike, do not allow the pitch attitude to increase after touchdown. However, applying excesive nose down on the elevator during landing can result in substantial forward fuselage damage. Do not use full down elevator."
Taking this into consideration, I would suggest a gentle forward pressure on touchdown. As QAVION suggests, a 2 degress nose down command should do the job correctly.
With regards to takeoff the Boeing book states the following,
"Light forward pressure is held on the control column"
Bearing this in mind I would say the the same amount of forward pressure be used for T/O and LDG.
All the best.
