Firstly you can have either saddles or sticks, whatever you prefer. Saddles is good if you later get a car that needs saddles.
Batteries it's really depends on your budget, most people have two and this is a good idea if you can afford. Take a look at je spares or mb models, they have a good range on their website with good information on! Don't advise buying a second hand battery unless you know it's previous history.
Charger wise I have the core rc uac 40, which is brilliant. Personally I'd check eBay for one or even the latest model the core rc uac 50, pretty sure there was one on eBay.
Hope this helps
