Rogue Audio Cronus Magnum hookup questions

I finally have my dream amp, a Rogue Audio Cronus Magnum, in my hands. I'm hooking it up tomorrow before a big party I'm throwing and have a few questions as this is my first integrated amp and I don't want to make a mistake.

http://www.rogueaudio.com/documents/Cronus_050413.pdf

1. How do I hook up my Energy S8.3 to the amp? In addition to the L/R speaker outputs, it has RCA fixed and variable outs. Which out do I use and how do I connect it to the sub? http://www.energy-speakers.com/images/download/360.aspx

If I can hook it up, do I just set the crossover active and to 80HZ as it is now?

2. If my phono cable that came with my Music Hall 7.1 is not long enough to reach the phono input(with built in stage) on the Cronus, can I run it through my separate phono stage and into one of the aux inputs on the Cronus till I can order a custom phono cable long enough to run direct to the Magnum's phono stage?

3. I also wanted to make sure that I can run the pre out on my HK AVR 325 into the other aux input of the Rogue so I can utilize the L/R speakers for TV and Blu Ray.

4. Finally, can I run the audio out of my blu ray to one of the aux inputs on the Rogue while also running an HDMI out of the blu ray to the TV? Or do I need to get a separate CD player for music and depend on the pre out of the AVR to deliver sound to the L/R speakers and sub via the Rogue?

Thanks in advance.

When putting the KT90 output tubes in my new Rogue Cronus Magnum, I heard something rattling around in one of them. The other three are quiet. Does that mean the tube is definitely bad and I should not power the amp up?

I wanted to have it up and running in a couple hours.

When I picked it up at UPS, they had the box standing on it's side despite arrows on the box showing it should be laid flat and fragile symbols. When I pointed it out they said "Oh we don't do that", referring to following handling instructions on boxes.

I don't see anything moving around in the tube. Just a faint rattle when I was installing it and when I give it a light shake.

Think it's ok to power up?

It's working and sounds incredible! I'm having some turntable issues but CDs and blurays are rocking in 2 ch.

@erikt - thanks so much for taking the time to respond on this. I'm setting up my Cronus Magnum ii and trying to dual-subwoofer it (Dual SVS SB-1000). I was wondering if you could help out on this? 

I fear I may be headed down the path you specifically recommended not to do: using slippers instead of summing cables.

My questions:

1) Am I correct that I'm using splitters and need to get summing cables? 

2) Should I use the VAR or FIXED out on the Cronus? 

3) Should I use the VAR or LFE input or just one? 

Thanks! I'm happy to message/email pictures if that helps.
