If you want to run your MC275's as mono amps (single input IN, and single speaker OUT) with approximately 150 - 180 watts output per amp, there are directions in the Owner's Manual for doing that.
What you are describing above (at least in your Par #1) is using two amps, both still in STEREO configuration, one amp for the mid/hi drivers in each speaker, and the other amp for the woofers in each speaker; This is known as bi-amping, and is a perfectly legitimate way drive your speakers, although most folks who go this route would use a SS amp for the woofers since it provides more control and thus better transient response from the woofers.
Your Par #2 (I think) describes running each amp as a single channel monoblock, one for the left speaker and one for the right speaker. Even without knowing what kind of speakers you'll be driving (a not unimportant piece of information!) I'd be inclined to recommend this as the preferred way to go -- especially since you already have the two MC275's on hand ;-)
