I suggest using a program called LithUnwrap. You can open x files with it and then convert them to 3ds format for example. Then you can simply import the 3ds object to almost any 3D program and edit the models with it. Then when you're done you save the model in 3ds format again and open it in lithunwrap to convert it back to x format. Set the convert mode to text and turn of compressed when converting to x format. Works nicely.

As for slots, open the slot configuration in the SlotModder. You can easily see if somethings wrong from there. Then check your ship data in the StartingPlayerShip or PurchaseShipPlayer and check that the slot layout is set right. Besides that I don't know why doesn't it work. I've made over 20 models for starfury and they've all worked with no big problems.
