Help with finding Linux apps for editing HTML/Movies/Images

[techlists at phpcoderusa.com]

Hi,

About 6 months ago I switch to Kubuntu and am trying to stay with Linux 
for my workstation.  I need to find a couple tools that will help me 
with that goal.  I am a LAMP dev not a designer, however, occasionally I 
need to edit am image or create a button. I also need to work with 
HTML/CSS.

Any recommendations on:

1) Graphics editor

2) Movie editor for YouTube tyle stuff

3) (X)HTML editor - would like a wysiwyg editor where I can look at the 
code and switch views so I can see what the HTML/CSS might look in a 
browser.

Thanks in advance for your input.  Please no flame wars.

Keith
