apt sources.list - is it right?

[yantux yantux <yantux@yandex.ru>]

Hello.

I need gcc for arm. Bevause I read http://www.emdebian.org/tools/crosstools.html and http://www.emdebian.org/debian/

After that I was correct /etc/apt/souces.list

Now my /etc/apt/souces.list is:

mydebian:/home/yan# cat /etc/apt/sources.list

# 
# deb cdrom:[Debian GNU/Linux testing _Lenny_ - Official Snapshot i386 DVD Binary-1 20081114-02:30]/ lenny contrib main

#deb cdrom:[Debian GNU/Linux testing _Lenny_ - Official Snapshot i386 DVD Binary-1 20081114-02:30]/ lenny contrib main

deb ftp://ftp.debian.org/debian/ lenny main
deb-src ftp://ftp.debian.org/debian/ lenny main

deb ftp://ftp.debian.org/debian/ lenny contrib
deb-src ftp://ftp.debian.org/debian/ lenny contrib

#deb http://www.emdebian.org/debian/ unstable main
#deb-src http://www.emdebian.org/debian/ unstable main

#deb http://buildd.emdebian.org/debian/ unstable main
#deb-src http://buildd.emdebian.org/debian/ unstable main
#deb http://buildd.emdebian.org/debian/ testing main
#deb-src http://buildd.emdebian.org/debian/ testing main

deb http://buildd.emdebian.org/emdebian/ unstable main
deb-src http://buildd.emdebian.org/emdebian/ unstable main



#deb http://security.debian.org/ lenny/updates main contrib
#deb-src http://security.debian.org/ lenny/updates main contrib


Is it correct?
What line I must remove and add for connect to embedian repositary and installing gcc for arm?

Thank you.

Best regards,
yantux.
