Hey I just got Project M 3.0.  And I wanted to finally do some Brawl hacks.  I think I may have an idea of how to do it, but I really don't wanna screw anything up or waste a lot of time for that matter.  So I figured I'd see if someone could walk me through it if possible. 

Here's what I've downloaded so far:

Characters (Models/textures) import:
-Ray V2.5 (It's a Fierce Diety look for Link.  The files are: FierceDiety.jpg, FitLink05.pac, FitLink05.pcs)
-Melee Ganon CBlissV2 (Melee Ganondorf colors for Ganondorf.  Has a bunch of .pcs files)

Full Characters:
-Ridley Psa Final ZSS UPD (Ridley character.  Goes over ZSS)
-No transform Samus (This is for the above so Samus doesn't turn into Ridley after a Final Smash haha)
-True Shadow the Hedgehog ver.13 (Shadow the Hedgehog.  I believe he's supposed to go over Donkey Kong?)
-Final Shadow OMEGA PACK (Also Shadow.  This one does have a readme for newbies so I may not need any help, but if anyone wants to make it faster for me that'd be great)

Music:
3 brstm tracks (I didn't get these from this site.  I think it was Brawl custom music.com?)

Also I'm going to use both Shadows, I want to try them out and see which one I like better.  More of the issue is that I don't know if I'm supposed to replace things in the Project M files with this stuff, or just throw all of this into the folders on this SD card.

Any help would be appreciated.
