Salome requires Aiko 3 complete.  The Aiko 3 you d/l from Cnet is Aiko3 LE.  You can use the texture that comes in the pack with the LE but the morphs won't work without the A3 morphs.  

GND is a morph for the V3 figure.  The base is in the Cnet d/l but you will need the head and body morph packs to make it work. 

Did you check the readme and the product page for required products before you bought them?  It's a good idea, especially when you're just getting started, to really check out things before you buy.  Don't get caught up in the "...oooh shiny..." thing.  If you don't know, ask here in the forums.
