I could use some advice on displacement mapping!

Hello,
I have a material which is 8 X 8 pavers in two versions 2048 pixels and 4096 pixels. they are meant to cover 1,36 M square at scale.
can you tell me how dense I need to mesh the surface of the geometry in order for the displacment map to function well but also keep render times reasonable? I thought 4 X 4 centimeter square mech should do it... but i am not sure.
The displacement map is subdivided by 6, pretesselated and not smoothed.
the displacement map is not detailed beyond just having the cement joints about 1 cm lower than the pavers. here is the displacement map I made,with a little 'flou' to round off the edge of the pavers and not make them look too sharp at tehir edges:
thanks!
Peter
PS: I think I need to find a good training session.. any ideas? somewhere in europe..; spain france, UK..
