Need some help here. How do i burn this properly to a Cdr-W? Also, what all does this do exactly? let me play backups with a unmodded xbox? with the orginal dashboard? What if EvoX is already installed, and I try running this?

Complex loader will not magically load up your xbox with out a mod chip off of cdrw.

At the moment the Pheonix Bios Loader is what you should be looking for. This wont boot up your xbox off a cdrw either. Read up on it a bit, then ask some more questions.
