Keith,
There are a number of ways to accomplish this. The easiest way, if the XML
document is not huge is the the XmlDocument object to load the XML into it,
find the location where you want to insert elements (either by parsing the
ChildNodes tree or by using SelectSingleNode()) and then simply inserting a
new XML Node with the data you need. This is pretty easy to do.
If the file is large (depends on your environment really - so test) you may
have to use an XmlReader and XmlWriter to read the content of the old XMl
doducment and then re-write the document as you go, adding the new content
as needed.
XmlDom is pretty simple to do - you should be able to find a sample online
easily. XmlReader/Writer is a little more non-obvious <g> and definitely
more work.
As for good books entry level books on XML I like Dan Wahlin's Xml for
ASP.NET developers which hits all the highlights in a very readable and
smallish book.

Dino Esposito has another one that's more complete and goes a little deeper
as well as dealing more with data centric issues:

I have and use both frequently...
