I'd still check the AC, it may well have had/ still have a leak.Also check the sensors (the little grills by the temp dials).
In terms of white smoke, I'd check all the usual (Do you have an EGR delete, if so did they blank it or leave it, if you can blank it also, all the map does is stop the signal, can still jam open) culprits, (MAP, EGR, MAF, Inectors), the uneven idle may well be related but yes, one or two of the glow plugs may have died (doesn't always show unless they drop their current, do the whole connecting across them, the tip should glow)
