No idea on the gearbox, unless it forces out oil which then gets on the exhaust.
Steering rack leak is common, and cure is a replacement rack. Make sure you flush out the old fluid properly from the system, and if at any time your steering fluid isn't a nice shade of red, then change it.
Oil leak - It is a M20, and if you can get it down to one minor leak, then you're doing well.
Most common source of oil leak at the rear top of the engine, is one of the D shape rubber bungs that blank off the hole in the head where you slide in the rocker shafts. Remove rocker cover to get at them.
