I usually wait 10 minutes before reconnecting the battery, but if you remove the neg terminal and touch it to the positive it should fully discharge the ecm caps right away unless they put in a series diode for protection of the ecm. In general I'd recommend 30 minutes to be on the safe side. The only things to reset are the clock and the radio presets. The TPM system will re-learn the pressures automatically.
I haven't seen any CELs so far from anything I did.
