JavaScript - In Search Of Better Slideshow, Or Tutorial

Ok, I wish to break this down piece by piece, let me see if I am understanding what I have done so far please, let me itemize my questions for uniformity and will create my very own tutorial out of these questions and answers for future use so I would appreciate any and every answer
to my questions below:

1] Which scripts or parts of it should be placed within the HEAD and BODY?

How will I know which scripts go into the HEAD and which should go into the BODY as I am
seeing some parts in the HEAD and some parts in the BODY?

2] If I want 3 things to happen and create 3 separate functions, are those 3 functions supposed to be listed in the order of how I want them to happen or does it not matter, for example, I want to first [a] create an ALERT then [b] ask for user to input his name into a form then if the user does it [c] another alert responds to the user. Let me label the 3 functions below as a, b and c.

<script type="text/javascript">
[a] alert ('Hello, I am your pet rock.');

[b] function touchrock () {
var username = prompt ("What is your name?", "Enter your name here.");

[c] if (username) {
alert ("It is good to meet you, " + username + ".");
document.getElementById ("rockImg").src = "rock_happy.png";
}

}

</script>

NOW, what if when creating the function and 2 Alerts above I were to list them in reverse or mixed order such as:

[b] function touchrock () {
var username = prompt ("What is your name?", "Enter your name here.");

[c] if (username) {
alert ("It is good to meet you, " + username + ".");
document.getElementById ("rockImg").src = "rock_happy.png";

[a] alert ('Hello, I am your pet rock.');

I am not asking whether the above would work or not but rather would this still be proper coding procedure or does it not matter?

I'm looking for a Javascript tutorial. I already have a good base in HTML & CSS. I'm trying to make a widget to display updated NCAA Football Team Stats.

Kind Regards,

Can any one help me to input the speed, accuracy and count to a database. I can't able to take the value because its JavaScript....

It should be this one:

Great class! they run you through the basics and have you do excercises on the site itself at the end of each chapter.
when you submit the code it checks the code and gives you hints if somethings wrong.

Very through and easy to understand.

Seriously folks, if your just starting or even if you think you know everything, you still might want to watch some of this.

ok. im done. no this isnt spam I dont work for the company, I jjust really enjoyed it.
