For music: You should use some good classic deathmetal like cannibal corpse, dying fetus, six feet under, autopsy, debauchery or other bands like Amon Amarth, Heaven Shall Burn, 8 Foot Sativa, Napalm Death, Kataklysm, Hypocrisy and so on. : )
While good bands those are...every suicide should come complete with a Darkspace/Sun O))) soundtrack for complete chilling effect.
