How many bottles and nipples?

I will be home for 8 weeks and plan to feed directly from my breast the majority of that time. However, I'm sure ill want a break now and then and let H feed pumped milk from a bottle. Baby is then going to full time day care, and I plan to pumps or day time feeds and breast feed in the evening and night. 

How many bottles should I get? Nipples? I currently have three 5 oz and three 9 oz Tommee Tippee bottles. This is in addition to bottles that come with the Medela PISA but I am assuming I will pump into those only and not feed directly from them.  I also got the Medela accessory kit and storage kit, but plan to feed from the Tommee Tippees.
