You can simply load your bundled js files asynchronously by using the Scripts.RenderFormat method as shown.

Scripts.RenderFormat(@"<script src=""{0}"" async></script>", "~/bundles/jquery")

Regarding your second question it has very minor impact on site's performance depending upon the bundle file size.
