Is there anyway I can disable sendmail on my various machines and configure mailx on them to utilize my Postfix SMTP server?
You might, but I'd leave sendmail in its default configuration of only accepting connections from localhost because a lot of other programs expect to be able to use it to send mail and it will queue and retry if it can't deliver immediately. Just edit sendmail.mc and point SMART_HOST to the server that you want to use as a relay.
