this isn't entirely in focus, the gray ends furthest away are a little fuzzy. are you planning on shooting the product in a light box? if you don't have one then get one (they're fairly cheap). and a white background too (a cheap roll of white paper works), some of the lightboxes are made with thin material and whatever it's on can bleed through the material. do you have a light source? if you're doing this on the cheap i'd recommend two identical lamps using the same exact bulb, one set on either side outside of the lightbox. this will keep your light and color somewhat even.
what lens are you planning on using? if you're not sure then what lenses do you currently have? you can probably get away without using a tripod, but it'll make things easier if you have a lot of products to shoot.
use aperture priority and set your aperture. i'd start with f/8 and adjust from there. if everything is in focus but you need more light then make the f/# smaller like f/5.6 or f/2.8. if you need more in focus then make the f/# bigger like f/11 or f/16. this will record less light so the camera will likely compensate by leaving the shutter open longer. if you're not using a tripod it make make the whole image blurry due to camera shake.
