IMO, this sounds less like oil consumption and more like shoddy work by the maintenance tech.
The rest of the issues- "smoke", noise, etc, are more than likely moisture evap from the exhaust and the HR "hiss", based on what has been discussed so far.
OP, keep an eye on your oil level. I would consider a quart or a bit under that (the distance from L to H on the dipstick) "normal" for around 5k miles of driving. More than that would warrant more attention.
