Guys, I'm having trouble with installing some mods. I'm attempting to apply the following together to Minecraft:

Lights Out [link]
Minecraft Forge [link]
Iron Chests Mod [link]
ModLoader [link]
Timber! Mod [link]

The way I use to try and install them:
-After downloading the mods, extract them to a file on my desktop which contains all my mod files.
-Open up the zip files the mods are contained in using 7-zip file manager.
-Open up minecraft.jar using 7-zip file manager.
-Drag the mod files over to the minecraft.jar.
-Delete META-INF.

When I was just using modloader and the timber mod, it worked fine. When I added in the other mods and Forge, minecraft froze on the "Done loading" screen with the bar most of the way full. Then I have to delete the minecraft folder and reinstall it.

What am I doing wrong here?
