Would you recommended New too monts shocks and bolts then?
I'm fitting top mounts because of the mileage and speed humps 

  Ive seen the top mount rubber split on lesser mileage cars.  Perhaps buy replacements that you are able to return if you don't need them. Not expensive at £50/pr     Bolts are stretch bolts which should be replaced once removed  They are designed to stretch when  torqueing into place.  
Regarding the shocks. Ive read of plenty of people installing springs while still using the oem shocks I suppose it comes down to age/wear of shocks and the cost. Replacing shocks springs mounts and bolts will avoid having any issues with the front suspension for some time to come
