Which would be better, to use the standard BYOND savefile, or a textfile. Please refer to my previous question of whether or not thousands of single savefiles versus a few large ones would be better.

Textfile or savefile?

If you're going to have size issues, go with a standard savefile. But for debugging purposes, be good to yourself and put in a verb to translate to/from text format so you can make changes if necessary.

Thousands of files, or a couple large files?

I'd say neither; try to find a solution between the two, using a moderate number of files of moderate size.
With player files, though, this isn't feasible, so go with multiple files.

What is the easiest way to create a decent textfile system that will read and create accordingly?

What precisely do you mean by that?
