Yes that look fine on the FET.
Quotedo i really need caps on the regulator.Yes I don't say these things for fun.Quotethe 5v one i use to power my servo is doing fine with out themNo it is not, it is just that you haven't noticed the instability it causes, it is not doing fine.

You need capacitors on those regulators, see the data sheet for exact minimum values but I would put a 0.1uF across the input and output of both regulators plus put an additional 47uF capacitor on the input of the first regulator.The FET needs to have the load connected to the 12V, so source to ground, drain to load, other end of load to +12V.
