Question 2: yeah man just use magic wand and click anywhere on the inner pink then select "magic eraser" which is loacted under your normal eraser simply click and hold over the eraser and it will be the 3rd option of the 3 that come up, then click anywhere inside the lasso you made with your magic wand, this will leave you with just the girl in the middle and nothing around her (will be gray and white checks) so you wont have a white background or anything


hope that helps, if you need more help just ask
