Understanding the Google removal tool

[zeus]

i have a question here, first i dont get when you add new pages to your site or images google fetches those in a couple of days, but if you remove pages or images they stay for 6-12 month sometimes, so now i need to use this removal tool, the question is

my domainname.com must stay, but i have some pages like my domainname.com/index.php or domainname.com/index/phpblablabla/ when i place those 2 last mentioned urls in removal tool, will only those be removed or is there a risk that my domainname.com is removed also.

I may be a bit old school ... I tend to 301 for most content and specifically 404 pages that do not have links to them hence or history to give them importance. ... Anything that gets indexed got juice from someplace and I am not eager to waste a drop. Webmaster tools will show what current links exist to the 404 after the content has been removed. But the page still seems to carry some juice for awhile - and for a longer while if it has a history on the site.

I would only use the removal tool if something got published which should not have. I am careful about publishing material so that has never happened.

domainname.com/index.php should simply 301 to domainname.com - that's it and that should do the trick.
