WebBrowser - Automating Form Submission Process?

I am automating a javascript web form submission process using webbrowser. I would like to use something without a UI but don't think httpresponse etc would do all that is needed. My code works but I think is not designed correctly. I think I should be breaking each step into its own sub or function. In its current state I think every time a page is refreshed/redrawn all the code is running which makes causes endless looping of clicking a link which is on its own destination page. What that means is click the link and the page refreshes with new information but does not navigate to a new page. So the code looks for the link and selects it over and over and over .... This I think needs to be subbed or done as a function instead.

Here's the code.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Part 1: Load elogging login page in Form_Load event
WebBrowser1.Navigate("[URL]")
[Code] .....
