Multimeter is not going to help with the O2 sensor (LAMBDA). That requires an oscilloscope which has a much faster refresh rate than your meter, or use of a scan tool.
The resistance on your coils however are not right. You SHOULD get a solid reading. If the meter display is walking around then you have an open....that's bad.
The MAF won't cause a hard misfire, it would cause crappy idle, hesitation, and crappy fuel mileage across the rev range. Not saying that it ISN'T your problem but with the reads on the coils, its NOT LIKELY your problem.
When you ohm the coils out you're are unplugging them and removing them from the car? (totally isolating them) If you're getting those reads then I'd say its time for a trip to the salvage yard with your meter and find some replacements. Then see what's what.
