Style tweaks to Main Store page

Hi guys,

Just not sure where I would find the CSS to tweak for a couple of things on this page:

http://www.linkedjewelry.com/the-collection/

1. The “select options” box – we can hardly see. The mouse-over color is actually what we would like to be the default state. Where to adjust that?

2. The product titles – if we wanted to give those color – where to adjust that?

3. Finally, the thin gray borders around each product – if we were looking to add color there – where?

Thanks so much –
