Removing najaasat

Q: 

  1. My question is that after intercourse I wipe myself. If some sperm gets on my hand I wipe it with a tissue then put my qamees on. Is my qamees paak or do I have to wash my hands before touching anything.
  2. If something is najis. Do you have to wash it 3 times and squeeze each time or until there is no sign of najasaat?

Wiping urine from the skin

Q: Please can you advise me with regards to whether when urine falls on my skin and I wipe my skin and ensure it is dry. If I subsequently perspire does my clothes as well as all the places I sit on (bed, chair etc) become napaak and do I have to clean these surfaces by wiping them thrice?
