Sounds like you're all set. I'd get the tester, though. Alwalys good to have handy and not expensive. Get the one with the short protection button. I like this one.

tester on Amazon

I use the same tester. It's cheap, simple, and does the job intended.
I actually had one of these. Tested all four outlets. All correct said the device.
