Question about law with collection agencies?

I am getting sued by a collection agency for a debt that was charged off 9 years ago. they want 2300 for a balance when it was charged off 289.03. i have my old credit report. They filed this suit in a state where i haven't lived in for 8 years, like 450 miles away. The court from that county in that state send a complaint and a response. I took it in to my attorney right away they giving me 20 days to respond. My attorney right away told me something is fishy. He sent this to another attorney. They claim the violated 3 laws one suing me in a state i have not resided in, suing me past the SOL and sending a post card with debt info i got a year ago. This company is NCO.. My attorney gave me a retainer agreement asking 35% of the recovery I receive. He feels the recovery to me will be over 1500. 1k per each violation. anyone hear of this? I just wanted not to go to court 450 miles away? but they will make that disappear too
