You should already have a program in your Menu called 'Converter' which will do most of what you ask... Although you'll need to enter currency conversion rates into it yourself first.

worldmate is great for currency conversion. you may have seen it in the Download folder on your phone. The pro version is payware, but u get currency conversion with the free version. You can update the exchange rates so that they are current and accurate, and convert between any currency
