1 - 10/W30 motor oil should be fine.
2 - yes but only fill to top of the core, anymore than that and it will expand when hot and boil over making you think something is wrong.
3 - tires have tubs in them. If one is leaking you will need to replace the tube. The valve cores have nuts to hold them in place, they are part of the tube.
