i dont know how long it takes to rebuild an alternator. i know that the kits are pretty cheap.....at least cheaper than a new alternator. it seems like it should be a pretty easy job once you break open the alternator. as for the battery b/c its sealed you cant check any levels on it. he was referencing if you have a battery that you can maintain by taking the caps off the top and adding water. you dont have that. dont stress that b/c you've got a warranty w/that battery so if it fries, get a new one for free.
