Your options are pump it down, cut it loose and clean it with red or yellow foaming cleanser outside or just replace it.
If it is heavily rusted you might cause a refrigerant leak trying to clean it this way though.

do you think thats why the water rushes to the back of the drain pan?

A dirty coil will cause water to be pulled like that.
Do you have a magnehelic? A pressure differential reading would help determine if you have a coil restriction.
I'm no fan of green coil cleaner. It might help a musty smell or a dusty coil but it doesn't clean a dirty coil.
If you are only speaking of a slope problem, that is an easy fix.
