in order to help solve your problems, we'd need to know what specific errors you are getting.

There are some minor changes from 2.x to 3.x versions of the JavaScript API, but by and large you can get away with using most of the same code.

The major changes I apply when converting from 2.x to a 3.x site are to update the dojo config module (as explained in the link you reference in your post).

Also, if upgrading to version 3.2, you need to include a reference to esri.css as mentioned in this page: What's new in 3.2
