Is there any safe way to double up speakers on my AV receiver?

AVFilter: Is there any safe way to double up the surround speakers on my home theater system? Any previous questions around this topic that I could find quickly spun into debates over "resistance" vs. "impedance" that I'm not able to apply to my circumstances, so I figured I'd try and ask this one straight out...

I've got a Marantz A/V receiver (SR7000) that I've successfully had hooked up to a full set of Boston Acoustics speakers for several years now. As we've moved between different houses, I've acquired two matching sets of the VRS Micro "surround" speakers (one black pair, and one white pair), and have usually just used whichever set better matched the house's decor.

In our new house, though, the room is laid out in such a way that it _might_ make sense to actually hook up both pairs at once--the room's basically a big "L", with the TV and central speakers in the central corner. I could pretty easily put one pair of surrounds at the end of each leg.

So here's my question--before I even bother trying to see if it sounds OK, is there any way to hook up all four speakers at once without overtaxing the amp? The speakers themselves are all labeled at "8 ohms", and the speaker outputs on the amp are labeled "8 ohms" as well. I could pretty easily hook each L/R pair up either in parallel or serially, but I'm not clear on the physics whether either approach is something I'd really want to do.

OHMS?

Amp/ Cabinet compatibility filter: Help with the OHM! I have a Kustom 250 head that says "3-4 ohms output". This connects to two seperate cabinets, one 4 ohms and one 8 ohms (2.67 ohms total.)
Will this fry my head?

What is the significance of the ohm value given on speakers? (ie. "400w at 4 ohm or 200w at 8 ohm")

How do find the ohm rating on a speaker cabinent?

Is there a way, without a meter to find out the ohm rating on a speaker cabinet? Is as easy as just putting the leads up to the input if you use a meter?
