host.conf : 

order hosts, bind
means search /etc/hosts first to resolve host names, then search dns. 
Name servers are configured in /etc/resolv.conf, if you don't have anything set up for a dns server, you can remove bind from host.conf.

You're right.  I've got no idea what host.conf is for.  nsswitch.conf is 
definitely the one being used:

% strace ping mv.mv.com
...
open("/etc/nsswitch.conf", O_RDONLY)    = 4
fstat(4, {st_mode=0, st_size=0, ...})   = 0
mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 
0x40014000
read(4, "#\n# /etc/nsswitch.conf\n#\n# An"..., 4096) = 1542
