yes. both texlua and luatex can be used without any additional files from a TeX distribution. You might need to supply your own scripts, of course.

texlua is for executing Lua scripts
luatex is for executing TeX files

You can run texlua by calling luatex with --luaonly (if I remember correctly)

Yes, but that's quite a lot of work. You need some TeX glue to start the Lua mode if you want to create a PDF.

Yes, if you know the position where the date should appear.

LuaTeX is well suited for this kind of task, but it seems that there is a lot of setup/programming necessary to achieve this. Perhaps there are better tools for that task?
