Drilled Tank - Now What?

I drilled my tank, (55 Gallon) it has two 1.5" bulkheads that I plan on draining to a sump approximately 6 feet below the display tank. The plumbing will be an elbow from the back of the bulkhead to ball valve (to regulate flow) then down to another elbow that goes straight through the wall in back of the display tank, sump will be under a stairwell down to our basement. Then another elbow will be used to enter into the Sump/fuge. I have a couple questions:
1. Inside the tank I plan on using a 90 degree elbow in the bulkhead facing up and a length of PVC to the surface of the water to drain. This will limit the water drained during a power outage but will it be noisy and is there a better way? The bulkhead is about 3" below the rim of the tank.
2. On the return I plan on using a DIY PVC spray bar just under the surface. The holes from the spray bar will be facing slightly towards the surface to agitate the water's surface. It will also limit the drain back of water into the fuge during a power outage due to it being near the surface as well.
3. I have two immediate choices for a return pump, a Rio 2100 and a Catalina Aquarium 5000. The flow on the catalina is just over 1300 GPH at 0' with the Rio being 675 gph. These are available but I am not against purchasing another pump such as a Mag or Quiet One.
4. For the sump/fuge I was going to use two tanks, I have a 20 tall and 20 long. This is a little confusing for me how to link them so I will probably just use the 20 long for a fuge sump combo. With that in mind the fuge will be on the far left of the tank with the water entering the fuge and middle section (housing skimmer) via a "T" with a ball valve to regulate flow in and out of the fuge. Does that make sense? Also if anyone has any ideas how to use both tanks with the 20 long being the fuge please lay it on me.
Hopefully this all makes some sort of sense to you guys. The tank is a 55 gallon that will be a reef tank holding LPS and Softies beside the fish. It will have 4 - 4' VHO bulbs with 2 - 10K bulbs, 1-50/50, and 1- Actinic. With the 10k's in front, then 50/50, and last the actinic by the back glass. It will also have a 3-4" Sand bed, with 55+ lbs of live rock. Am I missing anything? If you questions or comments shoot!
My head hurts thinking about all this stuff!

Thanks Guys!

1.5" bulkhead= 1320 gph
using cap5000 your lookiing at :
Total losses are 6.29 feet of head pressure, or 2.72 PSI. with a flow rate of 854 GPH
with 2 90deg elbows and 6' head and 1.5" return pipe...
soooo wont work.
use 1 bulkhead for your sump and the other for a closed loop.
you can combine your tanks for your sump fuge i'm doing the research on that right now..
it shouldnt be hard with a couple holes and silicone... i'm thinking about combining my 40breeder fuge with a 20g sump for my heater and skimmer. a couple 1" holes should handle my flow...i'm still brainstorming the idea. ...

With a ball valve on the drain line can't I adjust the flow down to whatever pump I choose to use? I am looking at another way to use both tanks for the sump/fuge as well. One idea I have is to use Spa Flex and two 1" bulkheads to connect both of the tanks. They would both be on the plastic garage shelves from Lowe's, considering they can hold the weight of both tanks. The 20 long (Fuge), above the 20H (Sump), on a shelf draining down to the 20 H and the Rio pump to return the water back up. Having the 20 H on a shelf as the sump would also alleviate some of the head pressure on the pump to the display. I need to draw this one out and do some more research on this one!

I am actually looking into drilling two more holes for bulkheads to do a closed loop for my UV sterilizer.

Do those ideas seem alright?

your right you could control your flow with a ball valve... also i think i might just try the siphon instead of drilling just to see if the flow will work...with two tanks before i commit and drill them..
