Sorry to hear about your plight. I"ve been away for a while hopelessly busy and so unable to respond to very much. I still don't have time to answer all your questions, but a couple of things should be said.
1. It would be very counterproductive for you to declare bankruptcy.
2. The lawyer was bluffing you. If your last payment was in 2005, the debt is stats barred and will disappear off your credit reports in 20011. If they really were able to sue you now and obtain a judgment, it would stay on your credit report 6 years from when it was rendered, not when you pay it off.
3. The process of writ execution is complicated and if you haven't been successfully sued, there's no point of going into it. But one thing I would STRONGLY advise: someone in your position NOT hide from creditors; it's better they know where you are. Certainly, a moot point right now as they must know where you live since you still have active trade lines going. What one creditor knows, they all know.
For completeness, you should make sure that no one has thus far obtained a default Small Claims Court judgment against you. Unlikely, but the sneaky buggers do it all the time. Contact the clerk of the Small Claims Court in your jurisdiction and give them your name to make sure. Those judgments sit around for 20 years and the writs to enforce them last 6 years. They can even be renewed AFTER they expire. To make matters worse, creditors sometimes file them BEFORE you manage to reaccumulate any assets (i.e., automobiles, bank accounts) or employment income or real property as a pre-emptive measure. These enforcement documents of seizure (or writs) are transferable as to the type of things that can be seized and also to the jurisdiction you reside in. Thus, if a judgment is obtained against you without your knowledge, it could sit around for years gaining huge amounts of interest. When you get back on your feet, that's when they usually strike. It's the stuff you don't know about that you have to be concerned with.
In contrast, given your situation, if any of your creditors had taken you to Small Claims Court and you were there to respond, you would have had little to worry about. Of course, they knew this already and that's why they didn't.
4. Later on, if you want to settle the debt, you can offer the original collection agencies or the scavengers who have purchased it from them, some percentage of the original amount of $2500. Forget the interest thing.
Maybe call up the old crowd and ask them if they want to get together at Shoeless Joe's to reminisce.
