Cyl #4 (I think, looking at it from the left to right, exhaust headers towards me, intake further back) - when I took out the plug, the socket itself was covered with black oil (Changed oil not even 5000km's back with fully synthetic again), the plug was full of oil - It was a mess. I had to get alot of carlton to remove it all before putting the plug back.

leaking valve covers are pretty common among all mazda motors. not the best design imo. in the case of the dohc engines you end up with a puddle of oil around the plugs. pays to wash/mop it out with a solvent and rag if you can get to it enough before pulling the plug or the oil (and any harmfull solids that found there way in) go into the cylinder.

Cyl #3, the rubber from the socket is stuck on the plug... It happened because when I tried to turn to loosen it - it was just too tight and the rubber just came right off when I took the socket out. Not only this, but as I tried loosening it (ANTICLOCKWISE) I heard a snap, crack and I hung my head.

if you mean the rubber coming out of the ign lead and staying behind, this is common too esp when they are soaked in oil. i also had this, but because i was using new leads i just picked at it with a pick (funnily enough) until it came off and then fished out the ripped up shreds of it.
if you mean the rubber from the spark socket? hmm
i tend to use one without the rubber in it, and a strong telescopic magnet to lift the plug because i dont trust them to not drop the plug and end up with porcelain in the cylinder and a dead plug.

Did I just do what I think I did? Heli coil time? Or did I break part of the plug itself? I can't see damage to the plug nor can I get it out.

hard to know
are you using a half inch power bar so you have some control and feel? making the job easier with a bigger tool gives you more finesse. i doubt that you stripped the thread trying to undo it. that usually happens when monkeys cross thread them on the way in or try to overtighten them. the plug is one piece from thread to hex, could it have been an extension or the ratchet slipping a little or something?
good luck.
