If you are exclusively pumping you need a high quality double electric pump. The best option is a hospital grade by Ameda or Medela, or a good double electric pump by Hygeia, Ameda, or Medela.
To begin with you should pump at least 8 times in 24 hours. Once your supply is established you can cut back your pumping sessions and see if you still get enough milk. Basically you pump as many times a day as it takes to get the total amount baby needs.
Give baby fresh milk as much as you can: your milk has the highest level of antibodies when your baby takes it directly from your breast, and is second-best when it is freshly pumped. The longer it is stored, the more of these antibodies are deactivated. Freezing destroys even more antibodies. (Your frozen milk still provides excellent nutrition and protection for your baby, just not as good as directly from the breast or freshly pumped.)
