Umm...yeah...every car does that really. They all need a little time to warm up. Just make sure you dont start going until it goes down to its usual idle

So once you car idles (settles down as you call it) the battery needle drops? I'd have to say thats an alternator problem...If you take it to autozone or something like that they can test it for you

my brothers car did this when he first got it, he said cleaning the MAF, IAC and idle control fixed it for him. Thats what I would look into doing if I were you.

+1, if not take it to Autozone, Advance, etc. and have them run diagnostics
