I've never used temporary adhesive for pattern pieces before. As far as marking details, that's usually done with tracing paper, found at your local fabric store, to do this, you will also need a tracing wheel. As far as the notches, you can either cut around the notches or cut inside where the notch goes, I usually do cut the inside, it's well within the seam allowance of 5/8. It's really not that hard, but it would certainly help you feel more confident if you had someone there to help, it's actually fun. I used to sew all my granddaughter's clothes. If you would like you can PM me and maybe I can help you along.
