example:

sm_gi @me 219 -1 69 5 0 1 -1 "134 ; 29"

will give me unusual milkman with storm effect

weapons:
here is full index list http://wiki.alliedmods.net/Team_Fortress_2_Item_Definition_Indexes

You want to give yourself the weapon, so you start with:
sm_gi @me

You want it to be a rocket launcher, so what is the item number for it (items_game.txt)? 18!
sm_gi @me 18

This is a primary weapon, so slot 1.
sm_gi @me 18 1

What level do we want it to show up as (0 to 100)? 75.
sm_gi @me 18 1 75

What quality (controls item title color and name prefix - vintage, community, valve, etc)? Community is #7 so:
sm_gi @me 18 1 75 7
(Note: this has nothing to do with the sparkle).

Preserve attributes? (Use 0 here).
sm_gi @me 18 1 75 7 0

Is it a hat? No.
sm_gi @me 18 1 75 7 0 0

What is the TF_WEAPON classname? TF_WEAPON_ROCKETLAUNCHER.
sm_gi @me 18 1 75 7 0 0 TF_WEAPON_ROCKETLAUNCHER

Now you add your attributes to make the custom weapon. Each attribute is defined like this: "Attribute ; Value".
So we want community sparkle:
"attach particle effect" is attribute #134. Particle system "community_sparkle" is #4. So our formatted attribute would be "134 ; 4".

Add that to the command string, and we have:
sm_gi @me 18 1 75 7 0 0 TF_WEAPON_ROCKETLAUNCHER "134 ; 4"
That should give you a level 75 Community Rocket Launcher with Community Sparkle.
