"also, is there an equivelant to "emerge world" in debian?"
apt-get upgrade
"but is there any way to update only things that have been found to be a security risk"
Debian does this with apt.

I haven't spent much time with Gentoo or it's documentation, so I don't know if they would have something similar in place.
"or at the very least is there a way to make a list of things i dont want updated?"
I know you can with apt, so I'm sure you can with portage as well.

There is also a distro called Arch Linux which is like Gentoo, only it uses pre-compiled i686 binaries instead of compiling from source. Might want to look at it before making your choice.
