Can someone please tell me what kind of memory card and battery charger I need to buy for my digital camera?? - fujifilm camera batteries great product

I have a beautiful little girl 8 weeks until I can no pictures of my battery, because they are dead. (I ask in this category because I know that mothers are clever and good for me anyway LOL)
I bought a Fujifilm FinePix F470 camera outside of eBay works well for the lithium battery, but died shortly afterwards, and only keep a handful of pictures. And I'm very challenged electroically! NP-40N, says of him, and with whom it said 3.6V 730mAh what it means, because every time I look at the battery in a pop on eBay, unless you give Fujifilm NP-40N.
Also this kind of memory do I need?

Ten points if someone can help! Thanks in advace!
