I have not looked at the datasheets for your specific devices, but in general you don't need any configuration of resistors - you can drive the gate directly from the PIC pin, as long as the pin can pull high and low. I do this all the time with N channel devices. If you intend to tristate the pin, you would want to add a resistor to the appropriate rail to make sure it is off (or on) in that situation.
If you need 100 mA, directly driving simply won't work.
