(1) iSight is hardware. Therefore, you will never find "iSight "
in your applications folder. Some of the software applications
that can use your iSight hardware are in this list:

Software that can use iSight uses it automatically when you
launch the software. Help for each that uses iSight will give
you more info about how to use the iSight in that app. For example,
launch an app like Photo Booth and search its "Help" for more info.
New apps that use iSight are being developed all the time.
You can search for other apps that use iSight for your
intended purpose with a web search or your Mac's > App Store...
menu command. Just be sure to verify that your system meets the
app's minimum requirements before you pay for any that aren't free.
(2) I have never used WebEx. However, according to its support page:
http://support.webex.com/support/system-requirements.html
WebEx should work with your iNtel MBA running OS X 10.6.8
As explained here: http://www.webex.com/howto/index.html
... Just log into your WebEx account to start or schedule a session.
Participants don't need to be WebEx subscribers to join you online...
A quick WebEx overview is at http://www.webex.com/go/us_quick_tour
In addition to the other tutorial videos available, there are also links for
on-line chat and phone (877-509-3239) support if you need more info.
