You should be able to skip the missions under mission select. The achievements do not unlock however unless you have beaten the individual missions.
For example: Let's say you want the Mile High Club Achievement but didn't want to play through all the missions beforehand. You can use the mission select to pick Mile High Club's mission and beat that on Veteran for the achievement without having to beat all the missions beforehand.
I hope I answered your question as i was unsure exactly what you were asking.
