i have oil coming ot of my exhaust and white smoke, what do i do?

i replaced an oil line from from the tank to the unit in the fender (passenger sie). I than added oil until i saw some on the dip stick. I started it up and drove a abot a mile to get it warmed to check the oil. I started to spit and sputter like it was out of gas, in the rear view i saw a huge smoke cloud. I shut it off, checked the oil and found it was to the top, and non was on the ground. I started up and took it home. I checked the oil it was still too high so i drained some off until it was right on the dip stick. Started and it made a smoke cloud again, this time i noticed oil coming out of the exhaust so i shut off and let it sit. After about two hours i strted it up again (it started right away) and pulled it in the garage. i later noticed a small pool of oil on the floor. So the question is, did a realy put in too much oil? If so what problems am i facing now?
