Studio update & theme options

I'm really excited about trying the new Studio Theme. I love the full width header, and the clean uncluttered look. I installed both parent and child (version 1.01), and activated the child only. I'm trying it on an inactive subdomain of my urban planning website just to get the hang of it. I have a couple of questions:

1) I noticed a new version is out - 1.02. Can I use the Wordpress built-in update function? Wordpress admin is not showing that a new version is available so there is no update link for it. If I have to do it with FTP, do I install all the theme directories I already installed - do I overwrite the existing directories and files or install in a new directory?

2) In Theme Options, it seems to be stuck on the tab "scripts." Nothing happens when I click on one of the other tabs.
