Need help with parameter handling in Google webmaster

[scottyboy]

Hi, I'm having trouble configuring my parameter handling preferences for my Prestashop as I'm not too sure what each parameter does but I do know that set correctly it will rid my site of any duplicate URL's. Does anyone know if these parameters are ok for Google to ignore when crawling my site or should I just leave them:

p
ml
n
pr
amp;id_lang
;p
;;p
;;;p
%3B%3B%3Bp
%3Bp
%3B%3Bp
amp%3Bisolang
%3B%3B%3B%3Bp
%253B%253B%253Bp
%253Bid_lang

Regards.
