Someone will probably chime in with some torque ratings for those action screw, but I can't remember the recommendations myself, and I don't have a torque wrench rated in inch pounds.
My standard is to snug them both equally, then tighten the front screw tight, but not to a gorilla grip level. Then I return to the rear screw, and snug it firmly, but not as tight as the front. I realize that this is an esoteric answer to your question, but it is really not rocket science. Snug them up firmly with a properly fitted screwdriver, and you should be fine.
