Regarding Support and Resistance Lines.... They could go down or up or toward eachother, it truly does not matter, All you are trying to do are finding points at which the price struggles to go below or above.
Regarding question 4.... Generally speaking no but there are a couple of exceptions.
If the candle which has gone outside the trendline is a news candle and its just the wick then generally you can discount it. However you need to check out the overall image and see whether it has altered the overall channel or if then specific spike the price action settled back into the range. If is the latter then you can go through the wick.
I'll tell you what should you article charts then I'll make remarks on your lines. Do not take everyting I say as gospel but its a tough idea.
