magento commerce template update

Hi, I already have magento template. The template was coded for magento version 1.0. Now theres newer magento version 1.1 which brings some small changes to template system. I need to modify magento ([login to view URL]) template to reflect: 1. slight changes in magento template itself introduced in magento ver. 1.1. Theres a need to base existing template on a new magento template version. 2. modify few things which was left unnoticedat the coding stage and now it start to play important role, basically: a) there are parts of template which dont react to language switching (mainly graphic elements like logo, block elements etc.). b) there are some glitches in presenting product page like cross-sell product wont appear in product page/ appear with some additional elements. c) some issues with check out process 3. Theres a need to clear css classes and add few new ones. Best regards, Piotr
