Unreasonable fee after moving out - Lexington Park apt, Columbus OH

On the day of move out (7/22/10), I asked the manager to inspect together but she refuesed and said that she never inspected an apt with a resident.

I cleaned everything and everything was working condition. So I was confident to show her my apt on t7/22/10.

However, the manager inspected on 8/1/10 which is 10 days after I moved out.

1) Now (8/28/10) I received a bill saying that garbage disposal is broken and I need to pay 60 dollars.
Why am I responsible for the thing happen after I moved out? When I moved out, it was working.

2) They gave me candle holder, towel, shower curtain when I moved in. So I cleaned everything and returned their belongs in a good condition where it was.
Now they charged me 30 dollars because I returned their items in a good condition and saying it is a garbage now for them.

3) They sent me the bill to the old address which is their apt address even though I gave them a correct new address.
Now they asked me to pay the late fee.

4) I paid all the rent fee before I moved out and I made sure several times.
Now they said that I did not pay the whole thing and need to pay extra rental fee.
I even asked them to give me a written proof saying that I paid all the rental.
They refused to do so before and now they are saying that I did not pay the whole thing.

This lexington park apt in columbus ohio is doing a sneaky business.
I am going to ask help from my attorny from my grad school.
