I'm actually using a loc line so I just bought this:

Can I just stick it onto my current setup and restrict the flow at the end of the output?
Please help! First drilled tank, overflow, and Sump. noooobbb here

Yeah... pretty smart idea.

It's counter-intuitive granted, but were changing the pump curve and dynamics by adding "head". I'm not saying it's an efficient method by any means. Hard to explain so I'll copy-pasta some stuff if your interested:
".... Another important point is that centrifugal pumps will require their maximum horsepower, for a given impeller diameter and RPM, at maximum flowrate on their Head-Flow curve. As the Head (or Discharge Pressure) a centrifugal pump is working against is increased (i.e.-throttling valve being closed, tank filling up, strainer clogging, longer or smaller diameter piping, etc), the flowrate will decrease and horsepower will also decrease..."

This one has a cool calculator too: http://www.engineeringtoolbox.com/horsepower-d_472.html
Hope that explains it a little better than I did lol

You don't need to restrict the flow of a pump that small and my advice would be not to. It won't be anywhere close to 900GPH after head-loss is factored in. I'm using an Eheim 1262 also rated at 900 GPH on a smaller 58 gallon tank, it runs at full speed.
You mentioned gurgling noise, bubbles, etc... That's the known behavior of a durso standpipe. Some will tell you to restrict the flow until it's quiet but chances are the flow will be insufficient if you do, at least if you're trying to turn over the water in your display tank at least 10x an hour.
You have another option that runs dead silent and will handle more flow but it requires more plumbing if you're up to it. Your tank is drilled for two holes already which is enough to run herbie-style plumbing if you run the return from the sump up and over the back of the aquarium. That's exactly what I did on the used tank I bought with a durso standpipe.
I can't cross-link you to another forum but there's a pretty good write-up on the site below and you can always google 'herbie overflow' for more pics and diagrams.
