Second, Whenever I was in third and then I approached a stop sign to stop, I hear two tapping sounds, it sounds like a hammer hitting something in the distance, like tack tack.

That noise is normal. The engine will do that if you load it too much below 1500rpm. Try to avoid doing that.
Firstly never let the revs drop below 1000rpm. It's okay to go below 1500rpm while in gear if you're coming to a stop, but you don't want to try and accelerate with the revs below that. There's no power down there. When you start from a stand still you need to feather the throttle until you get above 4-5mph, by then you'll be above 1500rpm in first gear.
I think that noise comes from the camshaft when it's not getting enough oil. The oil pressure drops when the revs drop too low.
