OpenLayers.Map object exposes a method call getLayersByClass. How do I use this method to retrieve all of the Vector layers from the map?
I tried map.getLayersByClass("Vector") but this returned an empty array.

Since this is the vector in this context... this.name will give you "activeInfo".
...
trigger: function(e) {
alert(this.name);
if (e.target._featureId) {
...
here's my console.log(this) within trigger function.

So your problem is that you're trying to assign the click handler before the layer has been created.
This Works. Here I have moved the call to the addControls(vectorLayer) function after you add the layer. This works fine. Notice I've added a layer parameter. This will make it easy for you when you're adding and removing layers.
Once you remove a vector Layer the handler is gone with it. If you add another layer, simply call the addControls(yourNewLayerName) function to add the handler to the new layer.
After struggling with it for about 6 hours I was able to get it to work. Here is the script I used to solve the problem:
lyrstands = new OpenLayers.Layer.Vector("Stands 1stQ 2012",
{
strategies: [new OpenLayers.Strategy.BBOX()],
eventListeners: {
'loadend': function (evt) {//THE LOADEND EVENT LISTENER - WHEN THE LAYER IS DONE LOADING...
map.zoomToExtent(lyrstands.getDataExtent());//ZOOM TO ITS EXTENT!
}//END OF THE LOADEND EVENT
},//END OF THE eventListeners BLOCK
protocol: new OpenLayers.Protocol.WFS({
url: "/geoserver/wfs",
featureType: "Stands_1stQ2012",
featureNS: "http://000.000.000.000:8080/OH_Layers",
geometryName: "the_geom",
version: "1.1.0"
})
});

The class should be
OpenLayers.Layer.VectornotVector. So your code should be:
