Some of the Google Wave UI components are very nice: table headers,
scroll view scrollbars, search field, panes with drop-shadow effect,
etc. Are these UI components available somewhere for general GWT use?

You have to go the extra mile and then some in that case. That said,

Yes, possible. You need to set the content type header in the
response from the JSP. In the case of PDF/XLS it is probably
"application/octet-stream" or something similar. You need to set the
header to "text/plain" or "text/html" depending.
