After changing the park light I reconnected the battery the wrong way accidentally. The car let me know by beeping and flashing its lights. I immediately corrected that fault. Upon completion I conducted a light test and found the park light not to be operational. But the hi low beam works. Tail light don't work but brakes and reverse do. And the pwr windows don't work.  the battery light, abs stay on when engine is started 
The only fuse that I've found to be broken is my 150amp fuseable link for the alternator.

Somebody please tell me it's the only fault

Reverse connecting the battery will not damage any standard filament lights. Can't say about the other devices.

try a hard reset by disconnecting the battery for over 10 minutes.
see if this will help
