Hi arlinaite.

1) Here's some information from the theme documentation:

Advanced: The dynamic styles will be added directly to the head of your theme. This is according to WordPress best practices, but if you do not want it printed out there, simply inspect the code of your page with the styling options set. Copy the CSS from head into your child theme's style.css file or this theme's custom.css (which you need to enable), and disable dynamic styling.

One downside might be that, if you want to change the dynamic styles, you may need to re-enable them and go through the same process of copying them to your custom css.

2) I don't know that there is a "recommended" or "best" configuration for this, or any other, particular theme. There are many posts and articles online discussing how to configure W3TC, or you might check on the W3TC support forum. If you have a specific configuration question you could post that in a separate topic and see if any of the other users here have any input. I don't use W3TC so can't provide much advice.
