220k should be fine for DT/SD for the moment. Really, you're in a "debug" mode for now, and increasing the dead time will help to ensure that you don't have a "shoot-through" condition. Having that long wire to your uC was begging for trouble; it could pick up noise inductively from other wires.
Sure, an electrolytic would be fine for the 10uF.
The main thing is the smaller 0.1uF cap. It takes care of the higher frequency transients. The 10uF cap takes care of larger transients, like when (eventually) your 3-phase induction motor is being powered by the bridge. Your currently "clean" 24v supply will start having lots of noise on it. The RC network, in conjunction with the Zener in the IC, should result in a pretty clean supply for the IC.
Next time you test-run the bridge, keep using the 1k resistor to the +24v supply to limit max current throught the bridge. Also, put another resistor (basically, 5k to 50k) from the middle of the bridge to ground. I can't yet explain why you were getting that 12v output trace (where the two 24v glitches were) - it may be a result of gate/drain/source capacitance. Adding a resistor to ground from the middle of the bridge should help to clear that up, and still keep your current levels low.
