I will take the second question first. I assume that the form is added in the Appearance -> Widgets page, in to a WooCommerce sidebar widget area?
You need to use a widget control/options/logic plugin to restrict which pages the form appears on, such as this on:
https://wordpress.org/plugins/widget-logic/
There many other like this. They would use conditional tags, such as described here:

The styling on the other form is quite extensive and custom. This would be outside the scope of our support, sorry. You would need to hire a third party coder to help you with this.
