Well, Adobe some time ago released a beta quality 64-bit native Flash Plugin player which seems to work quite well.

For example on a recent Ubuntu (mine is 10.04) these are the steps to use it:

1. remove the current plugin:

sudo dpkg --purge flashplugin-installer

2. download the 64-bit plugin from the Adobe site: http://labs.adobe.com/technologies/flashplayer10/square/

3. as root place the extracted file in: /usr/lib/firefox-addons/plugins/

4. restart your firefox and verify from "about:plugins" that it get loaded correctly

You are done! No more npviewer.bin segfault :-)

From System -> Preferences -> Appearance -> Background you can use the Gnome feature of using a special .xml file to accomplish this.
Togheter with this nice Python script (gnome-background-generator) you can simply automate the process of updating the files for new images in my collection (especially from APOD).
I put my background images in a dedicated folder and then I run from crontab this simple script:

0 */4 * * * $HOME/bin/gnome-background-generator -d 1800 --path $HOME/Pictures/MyCosmos/ --output $HOME/Pictures/MyCosmos/background.xml >/dev/null 2>&1

Then add the background.xml file to Gnome Control Panel and you’re done!
