Project 1: A new version of the Brick Breaker, that instead of nothing but gems, spawns randomly from all gems, all metals, and all tiny space rocks.

Project 2: A modded version of the Dive Well, but instead of the script to move you to the paired well, acts like a fountain of youth and, at worst is like swimming in Ambrosia, and at best, actually rolls your sim back an age category.

Needed information:
-What program would I need to get at the scripting for those two items?
-What game file is each stored in? I figure its in the WA files since those were both from that EP, but this will be my first endeavor into anything besides reskinning attempts, and I have no idea what I am doing yet.

Please ask modding questions in the Create forums (see Create > Sims 3 in the top menu). Good luck with your plans!
