1. just search Google for "cross-browser javascript" and you'll find what you need.

2. Impossible. Even if you manage to reduce it's functionality it will NOT be welcomed by your visitors. I personally close the window immediately if I see something like this.

3. You asked a general question so I give a general answer: focus() function works the same in all browsers (btw, IE and N are not the only ones existing, do you know it?). If it doesn't work as expected - search for errors.
It should be something like this:

[pseudocode]
. . .
if (document.formName.fieldName.value != [desired value or range])
document.formName.fieldName.value = "";
document.formName.fieldName.focus();
. . .

good luck
