How to eleminate redundant update process

We are using Microsoft Baseline Security Analyzer, Shavlik Netchk, and SMS to search for machines that are missing updates and then push the updates out to the machines. Our machines are located coast-to-coast with the server on the east coast. I feel that there is redundancy here in maintaining our network and wonder what is the best alternative. This is especially important to conserve bandwidth and advoid conflicting reports of update status. Any suggestions?
