My tank is 52x26x23 with an external coast to coast. My sump is a 40G breeder. My skimmer section just will fit the super reef octopus xp3000 I plan on running so it will be tight to fit all three drains in that section. I don't really want to have one drain in my fuge as it will stir up the DSB. Should I have a drain going to the return section with the return pump ?

No standpipe on the main drain but you could put a short length of pipe to extend up a few inches below the second drain standpipe if you want. This will prevent the entire overflow box from draining which may or may not be important depending on the size of the overflow box and the space available in the sump for back flow.
If you follow my recommendation then it would be best to put the main and secondary lines in the skimmer section if possible and the emergency can go in the return section.
