IMHO it should be 255.255.255.255. I haven't tested it for a while,
but the last time that I checked the netmask of an loopback interface
ment that it would answer all addresses by the network.
e.g. lo 127.0.0.0/255.0.0.0
means that the loopback itnerface will answer to all the
addresses in the range 127.0.0.0 - 127.255.255.255

I would guess that this one should be 255.255.248.0

That depends on what hostnames / ipaddresses you need to resolve.
It is possible that the answere is none. But if you are using
host names in configuration files, or doing reverse lookups for
logging or have tcpwrapper in effect then you will need to fill
in /etc/hosts. In reality, it doesn't really hurt to give
all the hosts information about all the other hosts in /etc/hosts,
that is unless it changes and /etc/hosts isn't updated accordingly
on all the machines. Thats really what DNS is for, but you don't seem
to want to use that.

That may be the cause. try using: ping -n <ip_address>
This should eliminate the need for any name resolution by ping.
