Australian first time buyer. Need a bit of help. please?

[GunbladeZero]

As I said, I am from Australia and I want to only make one order, I don't want to receive my custom blade only to find that I'm missing parts. I'm not sure if I have a sound board, motion sensor or clash sensor. I know it's kinda stupid to be getting everything on my first buy but as I said; I don't want to order my saber only to to come back and buy parts that I've missed. Here is what I have in my cart right now:

Hilt style 3 with guarded style switch hole

MHS ribbed extension v-grooved

MPS Pommel style 3 v2

Screw on LED blade holder style 4

SPST Momentary switch with red button

8-32 x 1/2" thumb screw

MPS Insert style 6

Could you also tell me if I've done anything wrong or if I need to remove anything? All your help gets me closer to my dream saber. If I do need a part, please send so I can add it to my saber. Thank you very much if you reply.
