Check out 'newbie questions? look no further' thread or goto the tutorial forum

here : DATA\Ships\shiparch.ini

They are both right. The ships stats are in the data\ships\shiparch.ini file. If you need help decrypting it - the beginners forums thread saying 'First post - check here!' or something simliar, contains a how to do this.

Once done, I would strongly recommend using Subxeros misc database (its stickied in one of the editing forums, possibly the problems forum, mod problems that is) to identify what the nickname for ships are. Then you can open the shiparch.ini file - and search for the nickname.

Once you find it, somethings are pretty obvious, others are not. For what to do, you will need to state what your after in more detail, or even better - read up in the tutorials forum

As I was about to email you tips on modding the ships, I noticed you have a fake email. Please change it to a real one. I'm pretty sure [email protected] isnt a real email

Did you mean the hardpoints or the infocard?
If you mean the infocard you have to change the infocard.dll!
To change infocard.dll you need FLED-ids.
To see what infocard you have to change, look into shiparch.ini
There the infocards are listed.
