Vanreefer nailed it.
I've generally found that anytime i go from a smaller pipe to a larger pipe in a return line you end up with micro bubbles. There is probably a way to reduce this with proper adapters, but general PVC ones have always given me micro bubbles.

The answer to #2 really depends on how much flow your return pump pushes. Check the manufacturer recommendations (should be in the instruction manual) to make sure that they recommend flow through 3/4". Usually the size of the outlet on the pump is a good sign - if it is a 1" outlet, chances are the manufacturer recommends 1" all the way from the pump to the tank with no restriction. The best bet if you can't find the information in the manual is to email the manufacturer for confirmation - most of them will reply to you within a few days.

Thank you Mindy, Unfortunately, the return holes in the overflow are already 3/4"; as I believe I went this route because loclines only go up to 3/4"? The pump is a Jebao/Jecod DCT-15000.

 You're probably ok as long as you run the 1" all the way to the bulkhead (it has 1" output right?). That said, I'm not the manufacturer.

Run 1" too the tee where they split to either bulkhead. outta the 1" tee use bushings to reduce down to 3/4 run the 3/4 to the bulkheads.after the tee the flow is cut in half no need for 1" all the ways to bulkhead unless there is only one return hole and in that case there's no tee.
