For my operator:
T/O flap is usually 5 but can be 15 now and again (rwy/weight/terrain etc)
Thrust reduction is usually 1000 ft aal but occasionally higher at some airfields where terrain is a factor (changed in the FMC)
Flap speeds appropriate for the conditions are on the speed tape. Just raise flap when within a few knots of, and accelerating towards, the marking (use the speed trend vector - green arrow).
Frankly, if you handle it like your 737NG you won't go far wrong.
