Absolutely, just give me a head's up!
For the access to the AC area, you can still keep that "aisle" on either side of the platform, it would just be a step-down on both sides of the bar. That way the doors on both sides can remain standard doors-to-the-floor.
I didn't really do much flooring isolation, it was too cost prohibitive for me. What I did do was isolate the stage, the riser, and the steps around the riser via Auralex Uboats, and filled with the SoftTouch insulation. Then, I had the carpet guy put in the denser underlayment (similar to what's used in apartments) to help deaden the sound. It helps quite a bit, but not to 100% sound isolation from the first floor.
For the fridge, if you go that route (I was also looking at the mini-fridges), there's some really nice ones that can be built into a wall, flushmounted as it were. That's another option, albeit rather expensive. Does look neat, though, with blue indicator lights...
Keep at it!
