XAP or ASPX or Mixuture?

I am using Silverlight since last 25 days and it changed the way of coding. I am embedding everything in xap which makes me little confuse.

My Question:

1. To what extend we need to write the code in aspx

2. If I am developing and ASP.NET application with Silverlight what proportion of code normally I need to put in XAML considering all pages are fully powered by Silverlight pages.

There are some fantastic tutorials including video tutorials found here...
