Connie, I agree with ALL these posts, but the first thing I noticed when I jumped in G+ was that I started popping up more in the SERPs. A LOT more!
That Google triad — YouTube, G+, and Google SERP — is a surefire power-boosting social strategy that can’t be ignored.
As far as circles go, I quickly found it was best for me to ignore all my circles except my main Social Media/Internet Marketing circle and my main subject matter vertical circle. It’s definitely more like LinkedIn than Facebook that way for me, with Facebook still being where my personal friends hang.
Internationally, I encourage you to add international contacts whenever possible. Over time, that divergent outlook will offer you many advantages over your peers who aren’t reaching out and eventually you’ll see your marketplace in much broader terms, too, regardless of whether your just a mom and pop local shop. Innovation, it seems, is pressing on somewhere in the world everyday. Don’t be the one to miss those insights because of short-sightedness, lol.
All in all, I’d have to say G+ gives me the most bang for the buck… the most overal exposure with the most opportunity for personal involvement (as Eileen mentioned). It really is the place to show your wares, you know-how, your personality, and a definite personal touch all in the context of ongoing newsy business day. I love it.
I don’t have as much knowledge as Eileen on this, but I learn from people like her everyday. Watch, learn, copy, personalize and innovate when you can. But whatever you do, unless someone appears to be an plague-spreading tomato zombie, add them and grow your main two circles. Can’t learn anything from anyone if you hide in a corner with the only friends you’ve ever known. 
Just my thoughts…
