works on magento shop

Hello, We need some works to be done on megento website: (1)Google analytics does not show correct data. It has to be fixed. (2) Some of the text in Dutch and French versions of the website is translated from files ‘translate’, which are located here: www / app / design / frontend / default / snsnino / locale But now the text is not translated from these files. Part of text on website is in English (you can see it specially on French version of the website). It has to be fixed. (3) The values of the filters are cached. For example, when we go to different pages on the website, we can see filters set by other users, like size, colour, brand, etc. When we clean cache, these values are removed. It has to be fixed that the filter values are not cached. (4) In Products close Wrap as a gift. But not remove it. Keep the possibility to open it later. (5) Change amount for free delivery from 50 euro (now it’s from 75 euro). And we need to know where we can change it ourselves, for the future. we can provide more detail info and screenshots if needed
