1. I set my h100 to 3.5 or 3.75. 3 seems to make it too weak and 4 is a bit hot. You could use that as a starting point. I do have the buttkicker though, so maybe you could get away with 4. I don't recommend anything above that, however.
Set crossover dial on sub to max, and set crossover on receiver to 80hz.
2. Definately start with the onkyo's audyssey calibration (with the mic). This will set the distance/delay/equalization pretty damn perfect. HOWEVER, afterwards manually set the crossovers lower. For some reason, (i suspect it is an audessy quirk, as I've heard it happening with other brands too) it will set the center at ~120hz when test equipment proves it can EASILY handle 80hz.
I personally set all my crossovers at 80hz for uniformity. Yes, the towers can probably go full range, but I want the sub to take the load off my fronts, and I don't want to risk cancelling bass by having the sub and fronts play bass simultaneously.
3. If you have the odd shaped HT-63 surrounds as I have, i recommend tilting them like I do in the pic I posted. The tweeter should face the listening position, the woofer pointed to the area immediately in front of you, and the passive radiator pointing out.
Originally I had them "straightened" out, making the tweeters face towards the rear. Your surround imaging won't be as good... I put in a couple live concert blu-rays (nine inch nails, and Incubus). The crowd in the rears were muffled (it was mostly treble).. but standing BEHIND the couch it was ear peircingly bright. I found that I could toe them inwards, turn the volume of the rears down, and get a "crisper" sound this way.
