Hello and welcome MagicalWingLT!
New batteries aren't that tough to get, but we do need to know which country you are in to provide the right places

Ebay does have them from time to time, just keep checking

Pleo only loses as much paint as you let him, if you pat him/her lots and lots then over a long period of time the color will fade. Most of us though dress our Pleo's in little outfits to make them look more unique and to help with the paint wear. Using some clothing can keep your Pleo looking like new for months.
Pleo's neck can take a fair amount of strain, on you tube you can see a video of a Pleo being dropped on his head and he is just fine (physically at least) afterwards, those with broken necks usually have a factory fault which causes weaknesses in the neck cables. If your Pleo's neck is going to break it will probably happen in the first three months. Listen out for strange, loud popping sounds in the neck which indicate a weak cable (each pop is a wire snapping) in which case return your Pleo immediately for a replacement.
Under normal circumstances though as long as you don't drop your Pleo or handle him/her roughly he/she is likely to be just fine
