How to install items?

[beelzemon]

I can install custom stages, Custom music, and custom characters.

But I don't know how to install CSP, CSS, and Items.

How would I install these?
Item: http://www.mediafire.com/?eunaln6xs21cjmd
CSS and CSP: http://www.mediafire.com/?42ny2nezfy0

Also I can't use Riivolution (USB Loader) I've heard that the only things that require it are sounds.

For item mods you need a common3.pac.

For Csp's look at the noobs guide (NG) tutorial in the tutorials and guides section.

Where do I get a common3.pac?

Bump.

Where do I get common5.pac?

[beelzemon]

I got my common3.pac now but where do I put the smashball texture at?

Do you have Brawlbox?  If not download it and search around.  I'm not quite sure where exactly it's located.
