Hi Natori,
Bleach: "lejia" is very easy to find cheaply at any supermarket. They have pine scented cleaning products as well, but I'm not sure if the make-up is the same as Pinesol.
For Thanksgiving I use a mix of Pepperidge Farm cornbread stuffing and their regular stuffing, but I have to bring it in the suitcase, because I haven't found it here. I' would imagine that the American shops listed further down the list would have them, especially at Thanksgiving time. I also like to make cornbread muffins, but I also bring the mix with me. I haven't found corn flour here. Instead, they sell "Maizena" which is cornstarch, a great product for thickening gravy or pie filling, but it doesn't have the crumb for cornbread.
Good luck!
David
