I went to start it and it goes click, click, click, click?

I have a 2001 Toyota Celica GTS with 41,540 miles on it. I went to start it and it goes click, click, click, click. The radio and lights all worked. My husband jumped me and it started. I drove it home and this morning it goes click, click, click. My husband was at work so I tried to jump it myself and I put the negative on the positive on the bad battery! I tried to turn my car on and nothing and the jumper cables started smoking so I took the cables off. I realized what I did wrong and put the jumpers on properly and the car started right up, but the radio is dead. What do you think is wrong and how will I know if I fried the battery? Thank you so much!!! Sincerely, HOPELESS GIRL
