Oil return line
Just purchased a 01 ap1 with a full greddy kit.. And was changing the oil and noticed the oil return line was going to my
Drain plug.. Is this lower than normal.? Or will it harm anything.

This is not "normal" it's a cheesey manner to accomplish the job and honestly it's not a good idea due to the drain angle IMO. I also imagine it hangs down rather low, which is another issue.
Mine is tapped into the side of the pan at 90 degrees.

Those are my changes.
Yes change the setup as soon as possible. Any of the above mentioned are fine. Make sure that gravity would drain the oil away, in other words the line should never go UP, only downward.

fluids dont magically defy gravity last time I checked
its the way greddy designed the kit, it will be just fine
use logic, think about it its impossible for the oil to "back up" in the tube
show me one a SINGLE case of anyone even claiming this was an issue a link please good sirs.

^^^theres a reason why no one taps anywhere lower than the highest level of oil. It's best to tap above the highest point, hence the girdle.
If using the oil drain bolt was the right way to do it, every single person would have done it, not to mention every performance company wouldnt waste their time drilling and tapping the pan in a different location.
Do a quick search on s2ki or any forum, you will see that it can happen, and is a common reason why turbo seals blow.

The oil drain line should be as clear and direct as possible to contribute to good disposal of the oil. The oil return line should never lead to the lowest part of the pan, instead, the higher the better to prevent any blockage. Remember, that the crankcase does have positive pressure at times. You need that line to be cleared and not submerged in oil, if you like your turbo that is...
