What is the best between a transistor and a pmos and which resistances
I have pain to make a choose between the NPN and PNP transistor and
  the P NOSFET example. What would be the best as far as I know, the
  transistor work with Ampere and PMOS with voltage.


The FET is better if you want to minimize drive current, but requires more drive voltage than a bipolar transistor. You have 3.3V available, so choose a FET which is specified for 2.5V Gate drive. 


  How can I calculate the value of R1 if I have a circuit of 3.3V.


The resistor is only provided to ensure that the FET remains off if the MCU output is floating (ie. set to input mode, which usually occurs on power up and reset). You don't need to calculate it, just use a value which is low enough to eliminate any leakage or noise on the Gate. 100k will probably be fine.


  if I opt for the two transistors, how can I calculate the resistance
  values for a 3.3V circuit. The output of the PIO I/O has 3.3V, of
  course.


R1 and R2 are are chosen to provide sufficient Base current to keep the transistors saturated at maximum load current. Divide the peak load current by the saturation Ic/Ib ratio of Q2 to get its Base current, eg. 0.6mA / 30 = 20uA. Then calculate R2 using Ohm's Law and taking into account the Base-Emitter voltage loss, eg. (3.3V-0.6V) / 20uA = 135k&ohm;. Now do the same for Q3 and R1, eg. 20uA / 30 = 0.7uA, (3.3V-0.6V) / 0.7uA = 3.9M&ohm;.        

These are the maximum acceptable values. Lower resistances will provide stronger drive and are OK so long as they don't exceed the I/O port and transistor current ratings, and you don't mind the extra current draw.  

R3 bypasses any noise or leakage that might cause Q2 to turn on unintentionally. It's value is not critical, but needs to be ~10 times higher than R2 to not steal too much Base current.

This two transistor circuit is only required if the load current is very high, the voltage being switched is higher than the control voltage, or you need a non-inverting output. Since you are switching low current and the supply and control voltages are both 3.3V, You could just use a single PNP transistor with Base resistor (Q2, R2), and set the MCU output low to turn it on.
