Try downloading the zipped source from the resource center. Unzip it and load the page in the "examples" directory. Does that work?

This is not likely to happen anytime soon. Your best bet is to post specific, targeted questions here (or better yet, gis.se) and work with other users to address the problems you're having (I'm happy to help however I can). There's also Esri support if you're an AGS customer. That being said, if you've been hung up for six months I would say it's time for you to re-define "trivial" or come to terms with the fact that maybe the JavaScript API isn't for you...

What browser are you using? Chrome with the JS console open or Firefox with Firebug on are the only two viable options for debugging, IMO.

When I run your code in chrome I get this error: Uncaught TypeError: Cannot call method 'add' of null What does that tell you? Since the only add method you're calling is map.graphics.add(), it's clear that function call is failing. You need to wait for the map to load before you can add graphics. Did you notice that the link I posted previously puts the code that actually adds graphics inside a function that runs after the map loads? Anyway, here's a working version of your code, which uses esri.geometry.geographicToWebMercator() to get a geometry that is suitable to add to the map: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

Check out what I posted a couple of months ago over on gis.se: http://gis.stackexchange.com/questions/2749/esri-json-polygon-ring-orientation/2750#2750 Also, esri.geometry.geographicToWebMercator() works for polygons so do something like this: var poly_wm = esri.geometry.geographicToWebMercator(myPolygon);
map.graphics.add(new esri.Graphic(poly_wm, sfs));

It's a pretty simple task to take the Toggle multiple ArcGIS Online services sample and convert it to use a radio buttons instead of normal buttons.

Can't be done...you'll need to publish your .shp file as a map service. The other possibility, if you're not dealing with a large number of features (let's say <1000), is to convert your features to .json, grab them and then display them as graphics on top of a basemap.

Your code is running before the esri API is loaded. Do something like this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript">var djConfig = {parseOnLoad: true};</script>
<script type="text/javascript" src="http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.1"></script>
<script type="text/javascript">
function init() {
var imageParametersPng32 = new esri.layers.ImageParameters();
imageParametersPng32.format = "png32";
}
dojo.addOnLoad(init);

Use a geometry service: measure polygon area and perimeter sample.

That code looks familiar ... I'm sure I've seen it somewhere before :).

Use: console.log("name: " + attr[displayName]); Your example code that fails is looking for a property named "displayName" on the attr object. The syntax I used lets you specify a property name as a string.
