Old/new website - same category URL! What to do?

Question

I have a problem. I bought an old domain name and I redirected all my content to it now.

So I have this category as example: http://www.formulawahad.com/category/news/ (or simply formulawahad.com/news/)

So any news link is like this: http://www.formulawahad.com/news/37329/

(My wordpress installed is not in the root - inside a folder).

Today, I got all the files from this domain which goes back to 2001. And Google found like 2000 errors. Now I want to upload them and make them available as they have a lot of backlink.

But the problem is the link of the old articles are like these:

http://www.formulawahad.com/news/090217_coulthard.htm

Or: http://www.formulawahad.com/news/080623_trulli.htm

So what do I do? create a "news" folder and place all html files in it? but then what will happen to my wordpress category formulawahad.com/news/?

I have the same problem with 2 more categories. So I need your help before I decide what to do.

Thanks a lot.

This is simple to get rid of those 2000 errors in google. In wordpress init() hook you have to make a redirect function. In databse add a table with old and new url,get url and search with old url and redirect it to new one.
