Setting up Content Type on Drupal

G,day i need some help setting up the content type fields to work with what i need. I currently have the following fields.

• 
  Title   Text
  Tutorial Link Text
  Thumbnail Text
  Description Text
  Website Author Text

Basically i would like to make the Title field be a hyperlink using the Tutorial Link field. And make the Thumbnail field become an image input field. I know im poor at discussing so i would like to set up the same system as what i have on my current site (link in sig)

Thumbnails
http://drupal.org/node/101748
http://www.kevinbridges.org/node/89

Title as Url
You will need to make a couple of tiny edits to the cck theme template if you don't want to do that you can use
http://drupal.org/project/contemplate
Which is dead simple to use I have example on my site

The CCK and Views tutorial I gave you covered most of this :D

well you have seen the template so you know how i would like the tutorials to be displayed. Is that possible with this module. thanks for the thumbnails i will download and install that now.

yes,

ok great im getting into it now.

righto i should be able to edit the files to get it all in the order i like without the titles on each and adding in a few images etc. But my next thing to do is the following

I would like to know how i go about editing the module so that when images are added the filename is edited with a few numbers and letters that are unique so that i dont have images with the same file name that would cause problems

still working on this
