Sorry if I sound a bit vague, but that's what comes out of half-knowledge
For getting the keys you use gpg so for the first one you do not have try as root.
gpg --keyserver pgpkeys.mit.edu --recv-key 010908312D230C5F
Then again as root once you see it imported.
gpg -a --export 2D230C5F | sudo apt-key add -
Now repeat for each of the keys you need and hopefully all of them have been uploaded to a keyserver that the mit.edu mirrors on their keyserver. If not then most times if you put in the url of the repository you will find an archive.key or a file ending in .asc this would be the file you need then you would use gpg --import http://www.????.LLL/path/to/archive.key
then use the --export to put it into the apt keyring you only need the last eight letters/numbers when exporting you can find these by using the gpg --list-keys
and it will show you them.
