I remember when I first started looking at pumps - it was pretty overwhelming. But if you're accustomed to doing Lantus/Log and understand the basal/bolus thing, then pumping isn't a big leap from there. Yes, you'll get trained before you're set loose with it. :-) It took about 20 minutes after dd's pump start to know deep down that this was absolutely the best, most life-changing thing we could have done. And you always have the awesome people on this board to come to with questions!
If you'd like to do some reading that will help make it all clear, I'd recommend Pumping Insulin. It's a great resource as you try to figure things out.
As for the Ping, I know people love it (we use MM, so I don't have firsthand experience with the Animas). All of the pumps are good, and they all do the same thing. I'm sure a local Animas rep would be happy to let you get your hands on a pump to just push the buttons and see what you think.
