I'd try reinstalling the driver just because that's what I usually do...

The scroll settings option lurks inside the touchpad control panel, if you are just seeing a normal mouse control panel then have a look at the pointing device hardware tab, the synaptics pad should be available. There may be a settings button, or right click on the device?

If the touchpad driver is installed, you can get it to show an icon permanently in the notification area. The icon is a rectangular sort of thing and is definately not mouse shaped. If you get the icon you can right click on that to get to the settings.
