SIMPLE introduction to themeing a view? PLEASEEEeeeeeeeeee!

Could someone point me to a simple tutorial on how to theme a page view? I.e. http://afterthemouse.com/gallery ?

I have the functions will override the given fields for just this view but I’d like a pointer as to how to do the following

1: let Drupal know where my gallery.tpl.php file is (thru template.php I assume but how?)
2: how is it best to atchive the equivalent of phptemplate_views_handle_field_Gallery_node_title etc.

I am sorry to say but as a noobie to drupal I find it hard to find simple tutorials for this sort of thing.

Many thanks
