It seems your first problem has been resolved since I clicked on the link you've provided.
But for you and any other guys who has the same problem, I've solved it this way:
First I've changed the template of news widget to display the title as a link:
Text='<%# Eval("Title") %>' runat="server" /> --%>
as you can see I've comment out the literal and add new DetailsViewHyperLink.
Then I came back to my RSS edit page and inside Content to include
section, click on change
button and select the news
page I am talking about (sample attached).
I believe you can use a same approach about Blog module.
Hope it helps.
