Sounds clutch / DMF or gearbox related if you are having issues getting it in gear when running. Check oil, coolant, power steering levels (I assume you didn't have an oil pressure light on or overheat?) just to be on the safe side. Make sure it is cooled down and try and make it home slowly. Once you get back I would suggest checking the gear box oil levels, if one of them is dramatically low then you may have cooked it. If G/B oils are ok then sounds like clutch but they don't normally smoke unless you have been slipping it a lot and they also stink a lot!
