Yeah I would agree with Jur on all points...
On the battery front, the new battery technology is great. I have a ton of Eneloops... and I have to recommend Thomas Distributing for your battery needs. (I have no affiliation) You will pay a LOT more in typical retail shops for the same thing. Thomas also carries the amazing Maha/PowerEx chargers ~ which are a LOT better than your usual "dumb" charger and they work with the Eneloop technology. The Maha Imedion ultra-low discharge batteries are also another good option - they are just like the Eneloops, although they have even more capacity iirc. You pay a slight premium for them over Eneloop of course, commensurate with the additional capacity.
I buy a lot online and Thomas Distributing was probably one of the best/fastest orders I have ever made. You will find them recommended via a lot of camera websites ~ since those photogs really care about their batteries.

Great source for those CR2032 coin batteries too... I saved a bundle!
