Thanks in advance
1. yes, I would think so since your sub has its own built-in EQ system. I've used MCACC with Velodyne's full parametric EQ'r built-in to their DD subs and the SVS AS-EQ1 audyssey sub EQ system. both work very well with MCACC.
2. I would say yes, since the more your room is already treated, the less radical changes the room EQ has to make. most experts say for best results, basic treatments (bass traps, 1st reflection absorption/diffusion) should come first. you are good to go

3. yes, no problem. I use an ext amp for the fronts and let the receiver do the rest & experience great sound quality. many folks use receivers as prepros with a 3, 5 or 7 ch amp and then use the receiver's amps for rears, wides or heights. the calibration & EQ system will take that into account. the models you are considering all have preamp outs for all channels so you can mate them with as many or few ext amps as you'd like.
and I agree, the models you are looking at: SC-68, 4520, 8801 are all top performers. sure, it'd be nice to see another new owner here, but all of them are very worthy contenders

happy shopping
