Scripting with text

Question

Hello. I have a few simple things that I want to know how to do in Illustrator with Java script so that I can easily automate it. I have looked at examples of scripts but most are too large and doing too many things for me to understand. If you can answer any one of these please do so.
1) How to determine the font size of text without having text selected? All fonts in my files should be the same size so this may require just testing the first text found, possibly by just scrolling through all of the objects until text is found. I would like to have the font size to be set to a variable that I can use it later.
2) How to set all text in document to a given font size and type? Let's say Helvetica, 6pt.
3) How to convert all text to black? I have some files that begin with gray text but I would like to take a whole document, scroll through each text and convert them all to black.
2) How to select everything and transform-scale? I would like to know how to scale with and without strokes and effects in script.
4) How to select everything and center it both horizontally and vertically?
6) How to insert the file name without extension and put into bottom right corner?
7) How to embed an unopened file and put into bottom left corner?
8) How to add a stroke of 1 px to inside edge of document?
Thanks for any help you can give.

This is probably NOT the fastest of methods of dealing with text but should be the easiest to understand… Should get you started.
#target illustrator
var docRef = app.activeDocument;
with (docRef) {
// Get a swatches color object by name
var myColor = swatches.getByName('Black').color;
// Get a text font object by name
var myFont = textFonts.getByName('Helvetica');
// Loop thru stories
for (var i = 0; i < stories.length; i++) {
// Then loop thru characters
for (var j = 0; j < stories[i].characters.length; j++) {
// Change character Attributes
stories[i].characters[j].characterAttributes.size = 6;
stories[i].characters[j].characterAttributes.fillColor = myColor;
stories[i].characters[j].characterAttributes.textFont = myFont;
