Change Currency, Text size and language

[Seer]

Ok I new at this but I understand it somewhat.  I am usinf a siteground template but I want to change the color and size of the text in the virtuemart categories to where it is larger and easier to read.  Also how do I set US Dollars as the default currency, right now everything goes to Aussie Dollars and when I go into the backend the language at the top left says Great Britain English and how do I change that.

I am using virtuemart 2.0 and joomla 1.7 is there a pdf manual yet for ver 2.0?

There is no manual, but all that you ask has already been covered in the forum. Some more than once.
