At 1000' AGL you usually set climb power... Reduce torque until you get about 550C EGT (but don't go lower than 80%) and reduce RPM to 97%. Flip on prop synch if you want and reset power levers to get your desired rate of climb or max. 650C EGT. Climb speed should be 160kt IAS until FL150, after FL150 reduce with 3kt for every 1000ft. Then during cruise, just keep RPM 97% and temp below limits, or adjust for fuel economy . During summer, be happy to get above FL100 with max weight. In winter you can probably get up to FL200 without too much trouble. Service ceiling is FL250, but so far, the highest I have flown is about FL190 on a 2+ hour flight. Shorter hops (about 1 hour or less) are mostly FL130-160. In the summer this can give you about 1-5 minutes at cruising altitude . Also, for some very short hops (10 mins or less) we just fly at MSA. About T/O and LDG speeds: Depends on a lot of factors indeed. Mostly weight and and flap setting. My company has a quick reference on the checklists that starts at 5600kg which will give you speeds of 99, 101 and 111 (V1+Vr, V2 and Vy Single Engine). Up to maximum takeoff weight of about 7050/7350 (31 or 32), which gives speeds around 112, 115, 125. Vref for 5600kg is 101 (flaps 35) or 111 (flaps 20). During approach 130-140kts is a nice speed, any lower and in the real aircraft the controls will get a bit more sloppy.
