I made a Severe Noob Mistake!, Battery, Alternator Options

[RavenAegis45]

So my battery was on its dying breathe and I went to get a new one, In my haste i accidently grabbed a battery that although looked like the one I had, but had its terminals reversed. Well stupid me plugged it in and cranked the Engine once. Well seeing my car didnt start I looked at the Battery and seen I had the terminals backwards. I exhanged it for the right one and welli figured the damage was done. I replaced several fuses that had burnt out, thinking that it maybe i was lucky enough to only have that done but well most of the fuses i replaced are ok but a few burn out the moment the terminals touch. After towing my car home I asked some friends and family what might I need to change. My dad says the whole Alternator cuz the regulator might be blown but i just wanted to get some honest opinions on what damage am I looking at?

And yes I realize I am a complete moron for rushing

you have to be careful when installing a battery and take notice of which ones are + and -. My old battery had the + on the left and - on the right when the label on top the battery was facing forward. My optima is the opposite, so the label appears upside down when you are standing in front of the car. Its easy to hook it up wrong if you arent paying attention.
