To add to what Argedion just posted, you (newer members of our root community) should want to learn how to do everything manually anyway. That's part of the fun and independence you gain from rooting. Not to mention, if something should ever "break" to the point of you not being able to access whatever third party apps you're used to using, what then? Start getting used to doing things manually, it'll end up saving your Evo one day. You'll appreciate being rooted, and learn so much more in the process.
Also, if you haven't already, follow Argedion's advice and ditch ROM Manager and Clockworkmod. You'll save yourself from a lot of headaches and troubleshooting that way.
