How to install mods for Minecraft?

I have Forge installed. I've been trying to install shaders and Pixelmon. Long story short, I have no clue what i'm doing at all. Please help? I have a skype if you want to talk me through steps.

Pixelmon - go to the start menu type or copy and paste %appdata% click the.minecraft folder and create a new folder and name it mods.
drag and drop the pixelmon folder into it and your done for pixelmon
Shaders -

remember that you have to change the profile on minecraft to the minecraft (what ever version it is most likely 1.6.4) forge (and the version of forge you downloaded)
