Getting started on the set-up of my new 265 w/dual overflows and sump. Quick rookie question. I know I will be priming and cementing pretty much every union I have in the plumbing layout under the tank, but didn't know if I should be gluing the standpipes in the overflows to the bulkheads on the overflow/tank side of the bulkhead? I was thinking to just dry fit those so I could remove if need be and if it did leak it would just leak into the bulkhead and sump anyways. Thoughts?
Glue/Cement PVC Overflow Pipes to Bulkhead

Correct, you do not need to glue the drain pipes to the bulkhead within the overflow. None of my three drains are glued to the bulkhead in my ghost overflow:
should there be gaskets on both sides of the glass/acrylic? I'm in a similar situation as OP, and trying to figure out how to properly set up my system.
I am in a similar stand situation friend. The bulkheads that came with the tank I bought are directly connected to the strainer....trying to see if I can get a PVC pipe to separate the two...but trying to figure out how to connect it, as it has a little wiggle room, but not enough for a coupling.
Please let me know how your set-up is coming along. Thank you.
I have researched for noise reduction, it is better to have the strainer higher? 
The main siphon being higher will not reduce noise per se. Higher main pipe will reduce water returning to your sump which can be a benefit if that is a concern for the amount of water backflow. I also use a flat strainer for my full siphon.
In terms of noise make sure the drain going into the sump is ~2" submerged from the sump water level. Also if the pipe in the sump is inserted to a bulkhead make sure it fits snug to eliminate air - that will eliminate noise too.
