General Modding

The Lepid Llama Unpacker by Echo

This is a fairly simple tool to extract the contents of a sims3pack exported file. Simply choose the sims3pack file when prompted, then select the file to extract and click the "Export Selected" button on the bottom left.

Postal- Package Editor by Echo Alpha

If you're joining in the fun of figuring out file formats and how to make mods, this is a pretty good place to start. If you're looking for content-creation wizards, this is probably not what you're after just yet. This is a very generic tool, for exploring the innards of the game's package files.
