We were getting lot of false positives. A network glitch would generate a bunch of 
PING alerts. I read that increasing the retries would force Nagios to stall when it is
retrying. 

My thought was, we would get alerts from the service checks if the host is down, so
the ping checks may not be needed. I am new to Nagios. So forgive if my rationale is flawed.

I think you are right on. That is quite likely the issue.

The hosts are pingable. So likely I will enable them.

Thanks.
