Layout problems, Currency switcher not working, image sizes

Hi Everyone.

I just had a couple of questions, i have been through the style sheet but cant seem to find the answer to my problems.

I need to put a buffer or margin on the left hand side of the breadcrumbs and category heading .
e.g

Home>Items
ITEMS

needs to read (without the dots)
.....Home>Items
.....ITEMS

Also where would i be able to adjust image sizes particularly for categories?

And finally my currency switcher no longer wants to work, i have relocated it to a different area and now the only currency that allows change is US Dollars...

Version 1.5.6

thanks in advance
