There are lots of programs that are capable of doing that, but I suggest you use
Blender. It is free and has lots of documentation, tutorials with a strong community.

Pandoras Box uses Direct X Objects (*.x). You can also convert *.3ds files from 3Dstudio Max using the Pandoras Box 3D Warper.

This process is called "UV-Mapping". You usually do that when you are creating the object in your 3D modeling software. To some extend, you can also use the Pandoras Box Warper for that.
