To follow your idea on using MOSfet, I found a web site talking about the IRF540, which is very similar to the one I have IRFZ44N., Except they use Pmos also, I guess I can use 4 Nmos and using an inverter instead of using 2 Nmos and 2 Pmos.
You got it, for the most part. In the end, you get 2 control lines, one for on/off, and one for direction. But, you will have to use 2 N's and 2 P's and an inverter (which you can also use a couple of small MOSFETs and a couple of resistors and make your own inverter from components rather than a 7404), N channel on top, P channel on bottom. Remember (in basic terms), N channel MOSFETs work by applying a ground to a circuit, P channel's apply power to the circuit.

And yes, some snubber caps and protection diodes, just in case. Motors are ugly in some ways...
