It is highly dependant on certain contributing factors, I will highlight a few here.
Generally speaking prices are increased over the Christmas period due to the demand on the product, though this is a broad statement and there are always exceptions.
However, some stores will go against this grain and lower the prices in a bid to sell more lower price units than their opposition; it depends no the competition on the product itself.
In the turn of the year, stores generally try to sell excess unsold units at a discount price to clear stock, this phenomenon comes in the form of 'January Sales' where people spend gift money and vouchers purchasing discount goods.
However, dependant on your country of origin this year (Notably England), the VAT will increase to 20% and you may even see an increase on December prices due to this.
yes
you got it all in one!
there are not usually set prices on set dates, prices change rapidly depending on many things. your best bet is to go and ask whoever is selling tickets. prices usually go up during special occasions eg. Christmas.
Because when gas prices go up, food prices also go up.
no
No, they only go up to Christmas Eve, but some go up to Christmas Day!
No, grocery prices rise with gas prices. This is because gasoline is used to transport grocery products to the stores from where they are grown or manufactured. If gas prices go up, then the cost of the grocery products to the store owner will go up and eventually the price the store charges will have to go up.
They are usually better after, when most prices go down and things go on sale. Though Black friday seems to be the best day for sales which is before christmas.

The Gas is making the gas go up
Stock prices go up or down based on the Demand - Supply theory. Whenever the demand for a stock is more than its supply its prices go up Whenever the supply of a stuck is more than its demand its prices go down
