Google and Robots.txt file

[noob_0001]

Do I need to put the stuff for all user agents in the googlebot section? Or will it apply the all robots to what it should not look at?
Yes, I have a htm on the list - use index.htm to prevent directory listing of all files and directories in a directory.

User-agent: googlebot
Disallow: /*.gif$
Disallow: /*.jpg$
Disallow: /*.ico$
Disallow: /*.png$
Disallow: /*.htm$

User-agent: *
Disallow: /cgi-bin/
Disallow: /banners/
Disallow: /images/
