Most of us have three environments in our organizations: Development, Staging, and Production. But I don't count Staging as a test system. Sure, I use it to do an integration test for code before it goes to the users, but that's not the only kind of testing I do. I install management and performance software, I run script routines and so on, and I need a place to check that just before I do anything on my "real" systems.
I'll point out software links on this blog, and you'll get those from other folks. I'll give you a script or two as well, and I normally warn you to "try this on a test system first". That's not an idle comment - you really should try any software or scripts on a completely throw-away system, one you can rebuild if needed with no downtime to production. I've had more than one package change a configuration on my test system that would have been quite...unfortunate if it had happened even on my workstation that I use to manage my systems. After all, that workstation is my production system for the job I do all day. Sure, it might not have affected the server (whew), but any downtime on my laptop is downtime to me, and I can't afford that.
I recommend a Virtual Machine for your testing. It is throwaway, doesn't affect anyone else, and it has the added advantage of being able to take a "snapshot" of the system before you try that script or install that software. Then if things go all wrong, you can simply revert to the snapshot and Bob's-your-uncle.
They always say a "word to the wise", but I don't think the wise need the word, do they? It's the rest of us that need the warning!
Counldn't agree more, especially the Virtual PC route. Love the product!
Virtual PC.. rightly said as throw away.. but somehow i face lot of performance issues with these VPC's..
Agreed. Good points.

Good question. Ready for a Bible lesson? :)
<A Href = "http://www.blueletterbible.org/Bible.cfm?b=Dan&c=2&v=21&t=KJV#comm/21">Dan 2:21</A> says "he giveth wisdom unto the wise"
Midrash Tanchuma has a <A Href = "http://books.google.com/books?id=9XFeKX1w50sC&pg=PA259">passage</A> on it.
It might also be worthwhile to look at Ecclesiastes <A Href = "http://www.blueletterbible.org/Bible.cfm?b=Ecc&c=7&v=19&t=KJV#comm/19">7:19</A>
