MIG isn't really the best weld method for in situ welding, not to mention upsidedown under the car ('out of position welding') because of the amount of spatter they can create even if the settings are well set for you, also getting the right angles on the handpeice while lying on your back is very hard and getting a neat weld will be difficult.

Oxy is pretty bad for automotive applications due to having an exposed flame being waved under your car and the confined space underneath your car could become extremely dangerous if you need to run in a hurry, also the amount of distortion produced is great because of the amount of heating needed.

Stick is problably the best option, even absolute begineers can get a decent weld, problably get a stronger weld than most cheapo MIGs could on even the hottest of their (very limited) settings. I recomend something like 'Satincraft 13' rods perhaps something in a 2-3mm would do a good job.

Also dont forget to remove all paint and oil, these can cause severe porosity, try to avoid heavy sticthing and full seam welding, heavy tack only (unless structual of course)

And yes, disconnect the battery.
