Unless you are getting some heavy-duty deals, you've picked a fairly expensive set of gear.
Atomics are good regs, but high priced. I agree with looking at the HOG regs; we have them and like them a lot. BUT . . . some of the issue is what you can get serviced, and whether you are willing to mail things away to get it done.
I don't like quick disconnects. We almost lost a dive in Mexico this last trip when my husband's started leaking. It's much easier to swap out a simple SPG.
And finally, you may or may not want to go with a console, and even if you do, I'd advise against putting your compass on it. Either wear the compass on your wrist, or put it on some kind of mount that you can clip to your BC. It can be quite cumbersome to pull a compass around on an HP hose, to a place where you can center it and use it, unless the hose is so long that it's rather messy.
I prefer to have my depth gauge on my wrist, where it is very easy to monitor during ascents, even when I have my left hand full of inflator or dump valve. But that's just me.
+1 on the Edge HOG regulators - Go to Cave Adventurers for that: HOG Backmount Regulator Package [HOGBMpkg] - $584.00 : Cave Adventurers!, We will NOT be undersold!!!. Give them a call.
and the BackPlate Wing (BP/W): https://www.deepseasupply.com/index.php?page=rigs Call them up, and ask for a guy by the name of Tobin. He will be able to tell you exactly what to get. Or, send a private message to cool_hardware52, that is Tobin here on the board.
Hundreds of tech divers can't be wrong about their rigs.
Lastly, for a tech computer that will work wonderfully up to before trimix, search for an "Aladin 2G Dive Computer". You should be able to pick one up for less than $300.
