For improving mesh after prism generation, you can use Fluent Meshing. 

In WB Meshing please export .msh file from File --> Export

Start Fluent in mehsing mode. Read .msh file. Go to Mesh --> Auto Node Move. 

Select all boundary zones and click apply. 

On prism layer thickness: it depends on what y+ you are targeting, what velocities you are using etc. 

In general 5 layers of prism layers should be enough for regular flows. Please try to reach aspect ratio of 5-10 for first prism layer.
