RHEL and derivatives uses rsyslog by default, so if you plan to use syslog-ng instead, you should remove rsyslog first. Other configs are highly depends on your usecase (like adjust kernel parameters for heavy UDP traffic and so on). Also quite generic people are facing with issues with selinux and firewalld but obviously there are solutions for any of these (other than turning off these services :))

Good aftenoon !

    I will install the syslog-ng OSE into a virtual machine with RHEL 7. 

    Is there anything I should worry about when installing on a virtual machine?

    Is there something to configurated on OS, before or after the install syslog-ng?
