At what stage would you dial in your flaps up speed ????
>>1st :Follow your SOP.
If you dont have any SOPs(unemployed) or don't understand them:
>>Normally the Acceleration in JAA land is 800FT as it is the end of the second mandatory safe climb gradient.(Boeing recommends 1000ft but for training only as it is easier to remember and works in 99% of cases)
>>The acceleration altitude can not be below the FRA (Flaps retraction altitude) from the Runway performance analysis.Most ICAO airports have minimum FRA below 1000FT(around 400AGL).However if FRA is >1000ft you have to use the highest of the two.

1. Would you just engage the autipilot ?
>>Most Airlines prefer you get the Flaps up before you engage the A/P.(min NG is 400AGL, Minimum CL is 1000 AGL).
Some airlines require you to engage the A/P at which the Noise reduction is to be started(NDP A :1500ft,NDP2/NDPB:1000ft,NDP1:>800FT).Obviously (N1 indication)reduced thrust (if you are heavy) will occur when you engage the A/P rather than selecting manually or waiting for the FMC preselected automatic reduction occurs.

2. press N1 and dial in maybe 210 kts ?
210 kts is ok for CL aircrafts below 57 T if i remember correctly,,,,check your take off mass before selecting 210...could be 220kts.
Press N1 if you havent engaged the A/P by then and if you havent selected the automatic thrust reduction in the FMS.
3. wait till I am at 1500ft (thrust reduction altitude) ?
1500ft works in most cases,watch for airports with NDP B for example.(1500ft would be too late to initiate thrust reduction/in some cases when you are light it would be a thrust INCREASE!).

Hope that helps,

regards.
