How Change the title to the cart module?

Hello everyone, I'm an Italian user and translating the component virtuamart I realized that all results except the cart module if you leave it in the paper position. I tried the style sheets in HTML files, but I do not find those strings that are to be amended: Shop cart, Items, Go to checkout. If someone wants to help me please, because I sent a ticket but I received an answer that only a user lifetime ... and I can not get the support. Rivogersi forum ... hope to resolve this problem.

Probably on ViruteMart forum you will get more more informations but this should be in VirtueMart language file. My advise is use some editor which can search phrase in multiple files, then you find all translations strings that you need.
