How do I change the shopping cart widget?

Hi! I’m setting up my MarketPress shop and I’m just about ready to launch. The last thing I want to change is a really nitpicky thing on the shopping cart widget. Instead of “Browse Products” I’d like it to say “Go Shopping!” And instead of linking to my Products page, I’d like the link to go to my main store welcome page at

I’ve looked through the forums and I’ve seen other (more complicated) shopping cart modifications, but nothing this simple. Maybe it’s not as simple as I think? Or maybe nobody else needs help with something so simple? Either way – if you can help me out I’d appreciate it.
