[Catch 22]

For starters, try the following web site- http://www.joyofwine.net There is some useful information there, as well as links to other winemaking websites that may be of more help.
As far as your questions
1) Coca Cola bottles would be ok, just a little inconvenient, as they are smaller than the normal container. As long as it's a "food grade" container, you should be ok.
2) As far as the campden tablets and the yeast, I would try to purchase them on-line since buying them locally is difficult. While you are there, you should buy a book about home winemaking as well. Also, at the following web site http://www.isgnet.com/ogwa/ you may be able to get help with making wine without chemicals.
Try to avoid using baking yeast if possible. There are specific yeasts for certain types of wines.
As far as the nutrient for the yeast, I don't know. The yeasts I use don't need that. I hope this helps.
