You had said at some point I'd need an additional secondary hard drive. If you think the one is enough, I'll hold off. If I were going to get another, I'd definitely get another LaCie. I'd planned on having another to add to my present set-up, rather than replace my current LaCie.

Having two drives (one outside your home) is a great way to keep your data safe.  It's a little bit of a hassle to trade them out from time to time but if you have the same manufacturer for both drives then it's less bothersome if the power cables can stay and only the drive moves.  I still don't like the cloud backup plans like carbonite and mozey just yet.  I'm not ready to recommend them until some things change around them.
