The JavaScript errors on the page relate to WooCommerce, not to Squelch TAAS. Try activating a default theme and disabling all plugins except for WooCommerce & Squelch TAAS, I think you should find no problems at that point.
If you’re still having issues then I need to know about it because the plugin should be 100% compatible. But I develop the theme against Twentytwelve (and Twentythirteen now that it’s out) with WooCommerce installed and activated and I’ve never had a conflict. If I did it would be dealt with (assuming it can be) simply because I need the plugin to work well with WooCommerce.
