sounds like the pcb in the back of the dash has gone
if the battery light is on that means the battery isn't getting charged so i'd be carefull of how far you go in it like it is

all the dash lighting etc is controled by the dimmer switch so thats the first point of call
after that, pull the dashout to see if there is power going to the back of it, i'd assume not which is why nothing works on the dash but other stuff (like the glovebox) do
the clock is in with the same sort of curicit to that explains that one

other than that, there are a 1,000,001 things tht can go wonrg
