Need a critique of a layout I'm debating using. And possible mods to it.

That's the layout. Here's the situation
- I can do 2 classic panels if I want.
- I have an Arkanoid, an Oscar Vortex, and 3(!) OmegaRace spinners (but no way to interface the OmegaRace's to a PC I don't think) - I'd like the Oscar and Arkanoid each to be on at least ONE CP as there's a huge difference in their feel and I love Arkanoid.
- I'd like to have a dedicated 4 way on the classic.
- I don't care about 2 player 'side by side' on the classic (Should I? Are there any simultaneous old school games that my fighter CP wouldn't handle?)
- I have 2 U360's. I was going to put both on my fighter CP - HOWEVER - I'm up for moving one (the 2p one) to this and replacing it with an 8-way if it would make controls 'work' better.
Here are the questions:
- Thoughts on double spinner placements on the above layout?
- Buttons: Good? Less? More?
- Joysticks: 8 ways? (See situation above - I'm not buying anymore U360's at this point).
- Opinions on a third layout being a dedicated 4 way and dedicated 2 way? (If so, how does that change my needs for the above panel?)
- What layout am I missing?
Note that short of a 1.5" trackball, which I am pricing out now, I can't do a trackball in this cab because of depth/angle issues relating to swapping the CPs. So....spinners, joys and buttons are the ingredients. Also, I am willing to buy an interface card for the OmegaRace spinner (and would like to have a working OmegaRace CP as the third CP) if it's possible. Haven't seen any hacks for the POT based spinner yet though.
Your input is requested sooner rather than later - I'm tired of hemming and hawing and I want this cab finished by the end of this month.

---steaming pile of meadow muffin---, I already think I'm up for a longest active member that can't finish a damn cab award. :/
Oh...few more 'complications':
- I have two flight sticks I can jury-rig mounts for (they aren't tron sticks, but...they'll work at this point).
- I'm willing to buy a Push/Pull Spinner.
- Assume I'll spend whatever on controls - except for the noted buying more U360's - to get this done. Embarrassment at not finishing it is overcoming thriftiness.
