I would suggest that the 37 C recovery is helpful -  its the Shaking part
that may be adverse to the proceedure as you are trying to gain entry of
you Dna into the cells -  but if you treat them too harshly (shaking?) 
that this may not be of assistance. I've plated immediately and after half
hour stationary incub. the latter certainly gives you better results but
the former works when you're in a hurry!
Good Luck
