Mazda 6 2.3, Put Too Much Oil In Engine

I have a 2007 Mazda 6, 2.3liter, I did the oil change today. The clerk at the parts store told me that this engine takes 5 qts. So I poured all 5 qts in. I tried to drive it around the block, and it started to spew white smoke, and was powerless. I got it back home & turned off the engine. At first I was perplexed as to what was going on. Then it hit me that it was probably too much oil. I called a different parts store, & they told me the same, "5qts". I asked if he was sure, so he checked a mfg. website, & found that it calls for 4.5qts. I plan to drain the excess oil in the morning & clean the plugs.
Is there anything else I should check? Air filter box, breather tube, pvc?

Could driving it around the block have caused any serious damage?

Thank you in advance for any & all answers!
