The answer depends on what look you want. Do you want to paint the cabinets or stain them? Do you want to make laminate countertops look like marble or granite? Do you want a tile back splash or something different?
Take one of the doors off and take it to the paint department of your home improvement store. Look at the cabinets they are selling and ask their paint pros what you need to buy to copy that finish/design. They have all of the latest paints, stains and finishes and application tools for a professional job. And they have great ideas!

Paint for the cabinets.
Make sure they are clean and dry. Remove the doors and hardware. Mark the doors and cabinets with tape where they go. Lightly sand the doors and cabinets to remove any gloss and roughen the surface for paint with 120- to 220-grit sandpaper. Use a tack cloth or damp rag to remove dust after sanding. Prime with a stain blocking primer like Zinsser 123, KILZ,or BIN and have it tinted to the color of the top coat. This will prevent dark or stained surfaces from showing through the top coat. Acrylic, or water-base, paints are low-fume and clean up easily with water. Alkyd, or oil-base, paints require good ventilation because the paint contains solvents that can irritate your lungs and make you feel sick. Alkyd options require mineral spirits for cleanup, but they provide a hard, durable paint finish. Whichever you use, buy the best-quality paint you can afford for a lasting kitchen cabinet finish. Seal with at least three coats with a water based polyurethane. Use a small foam roller and foam brush for a smooth finish.
