First question first.
You are right. I mess with my server way too much. You are probably much better off. First do no harm remember. But, I like to tinker and that means playing with it a bit.
A few things come to mind:
1. definitely updates
2. make sure backups are working
3. not sure which server you have. Microsoft has free tools called Best Practices Analyzer.
4. check error messages, but don't freak out over each one.
5.Also call your computer company, Dell, HP or look up in manual. They have free software to monitor your server
