About the CV, make sure it looks good. A photo is probably OK, make sure it's a good one. Spelling and grammar must be perfect. Have just the right amount of text on each page: no large white areas, nor densely packed with text. Not too short, nor any 20-page wonders. Use good quality paper. Never exaggerate or gild the lily in a CV. I get lots of CVs sent to me and I can (and do) trash >50% of them before I've finished the first page. I would cover all tattoos. And what magnumPI said. Good luck.
