When you want to update the buttons call:

currentRibbon.Invalidate();

The currentRibbon variable can be populated with:

Office.IRibbonUI currentRibbon = null;
public void ribbonLoaded(Office.IRibbonUI ribbon)
{
currentRibbon = ribbon;
}

This requires your ribbon xml file to have the onLoad="ribbonLoaded" on the
root tag.

Then in your ribbon xml set the button property to get the enabled state by
calling a function such as :

getEnabled="IsEnabled"

Then create your IsEnabled function which will return true/false depending
on whether the button should be enabled or disabled.

Hope this helps.
