Does the program do a VST Scan when you first open Sonar? (it should) If not you can do it manually. Go to Preferences/File/VST Settings. Here you can set-up the VST Prefs for when you open Sonar.
 
The main way to keep track of your plug-ins is the Plug-in Manager. To open it go to Utilities (on top) and click on Cakewalk Plug-in Manager. Here you can keep track and manage all the VST's, Direct X, etc.

I see no sign of it installed on my system. I would expect to see it listed under Programs and features in Control Panel, but it's not there, not do I see a folder in C:\Program Files or C:\Programfiles(x86). Perhaps I need to reinstall. Another interesting thing I notice is that Sonar Platinum is not showing up under Programs and Features either. But it does have a folder under c:\Program Files, and it's been working since my initial install... weird.

Did you do this yet?

Yeah, what he said. 

You guys rock... thank you!!!

Well, I was able to get everything installed over the weekend. Took it for a quick test drive, and was able to get drums playing, I could not find anyplace to adjust the tempo...  I'll take some time tonight to try again, but can anyone answer that one for me?  Thanks again for the help.

Your BPM is displayed in the  control bar.  Click on it and you can change it.  Or, under views>tempo.

There's a zillion way's to use a Soft Synth drummer. 
Everybody here does it differently and for different reason. 
But the basics of it haven't changed in 30 years. 
Midi notes trigger the different pieces of a drum kit. 
You can find millions of pre made drum loops and use those
Or like me and many others, you can play the part on a midi keyboard ( or better yet a digital drum kit) and make your own parts. Just bang along using a scratch vocal, guitar and the metronome. 
I have worked that way for 30 years so for me loops take to long to build. But many are good with loops and know where to find the ones they want. It would take me all day just looking. 
 
I also have some of my old Roland 505 Drum patterns I use to start a song out with. I guess those are sort of loops. 
So welcome to the wonderful world of creating realistic drum parts. We have all the tools so there's no reason to have lame sounding drums anymore. Nobody wants to listen to a recording that uses a drum machine. 
 
Here's a cool trick.
Mike up an armchair left and right arms with 2 mikes. 
Record this to 2 mono tracks in Sonar. 
Sit in the chair and play the drums on the arms kick/snare. 
Now drag those tracks to a midi track and Melodyn will create a midi track of your drumming, A pour mans digital drum kit. 

So, in EZDrummer, there is actually a place in the software that I can set things like Time signature and tempo. I can not find the place to do that in AD2. Adjusting the project tempo does not effect AD2 at all. Not sure if I am missing something, but I tried last night in Stand alone and as a plug in and cannot seem to adjust tempo at all... has anyone done this???

There should be a setting somewhere in AD to "follow project tempo."  I'm not at my DAW today, so can't confirm exactly where it is.
Once that is checked, AD will automatically adjust to its host's tempo.  It's really handy if you're auditioning beats, since each pattern is set to reflect the speed you want the drummer playing to.
