Problems with WP E-commerce category

Hey guys,

So I’m having a few problems with my category in my left sidebar.
This is my website:

I’m using the WP e-commerce plugin.

I want the category to be extended when I hold my mouse over the category.
When I hold the mouse over the iPhone category, I want it to extend all the sub-categories.

If this not is possible, is it possible to make it extend the category once you click the head-catory? Like clicking the iPhone-category will extend all the subs.. Now, when I click the iPhone-category it leads me to all the products from the sub-categories.

I’ve installed the plugin WPEC extending categories without success and Collapsing categories, but I find that one ugly because of the weird lines the category.

Another thing: In the right upper corner at my cart – most of the text in the cart and checkout is in my main language, but some of it hasn’t changed. Is there any way to solve this?

Thanks in advice!
