The nails you have will be fine, you can nail both vertically in to the timber trimmer supporting the rave sheet and horizontally in to the stud as required (approximately 600mm centres). To reduce the chance of splitting the quad (this might sound silly) first attempt to hit the nail in backwards this will leave an indent in the quad and flatten the tip of the nail. I used to use this method all the time and it is common practice when there is no nail gun handy.
