Cold is easier to tackle than Hot; you can just add more layers.
The most important thing is to keep dry; buy/rent water and wind proof equipment.
Prefer buying a lightweight coat under which you can add layers (t-shirt, long sleeve, sweater...) instead of a big bulky coat.
You can also get boot covers that will protect the lower part of your pants if walking in the snow.
Mittens vs. Gloves: Mittens are warmer (and cheaper) at the cost of a loss in dexterity.
Mufflers ? don't know about that.
Money belt, why not; not a big issue; just keep some loose change in easy to access pockets so you do not have to remove all your cloths to get to it.
Food: Just eat what you are used to eat when you are in town; hot food is always comforting but not practical when hiking; get granola bars (nuts, chocolate...) they keep well, and can help you get some energy into you if getting hungry before getting a proper meal.
Soup Powder? yes, soup is good, but will you have access to hot/boiling water ? that is the question.
Drinks: Water is always the best choice, if seriously hiking, maybe a "sport drink" can help in the long run.; hot chocolate/chai is comforting
If doing day-hiking (get back to the hotel each night) , your best bet is to only bring dried food (nuts, granola bars, chocolate, dried fruits); don't bother with soup powder, noddles... accesss to hot water will be problematic.
