Launcher Pro does not seem to be availabe from the Marketplace as of this post. Maybe an update is coming. Also, you metion Google Search version. How do you determine which version is installed.
for thoes who are running 2.2 and LauncherPro-

if you use the Google Search Widget make sure you use the "Google Search" (bottom) and not the "Search" (top) widget-
idk why the Search widget is even a option if the Google Search is the upgrade-
