From your experiences can anyone suggest a good quality shock absorber for front and rear of buggy obviously not to stiff on the front I'm guessing standard for the front thanks in advance 

Front shocks depends on your ride height. If I not lowered then standard as you say. Most of the usual suppliers seem to sell Cofap brand which work well. If lowered (unless you've got drop spindles) then I usually go for the shorter Empi/Bugpack oil damped units.

Avoid coil overs, at least on the front end.
