First Saber! How Am I Doing?

Greetings fellow sabersmiths!

I decided that I'm going to try my luck at constructing a custom saber, and after looking at my different options I settled on TCSS. I'm going for a saber with electronics, sound, and a blade. I just wanted to post my parts list here with a few questions to get y'alls ideas/suggestions

Here's what I have so far:

Blade:
Corbin Battle Blade, double wrap, bullet tip
(what blade retention screw will I need?)

Hilt:
Blade holder style 12 w/heatsink
Hilt style 3 w/16mm AV Switch hole
MPS Pommel Style 7
MPS insert style 1
MPS Clip
16mm Momentary Red Ring Switch (primary)
16mm Momentary Stainless Switch (aux)
5/8" D-Ring

Electronics:
R/G/rB Cree XP-E2
18deg Cree Star Lens
Prizm Sound Module v4 (so I can color change and some other stuff)
28mm Bass Speaker
Thermal Tape x2 (in case I mess up the first one)
MHS Speaker Mount v4
28 gauge wire
.47 ohm .5 watt resistor (x2 for green and blue)
1.2 ohm 3 watt resistor (for red)

Battery Option 1:
Li-Ion Batteries
18650 Single Cell Holder
OR
Battery Option 2:
4AA Battery Holder with mount (this wouldn't include speaker mount)

Also, I'm not really sure how to get heatshrink (which heatshrink do I need?).
Thank you all so much for your help

You will need a resistor for your red AV switch.

I would go 18650 over the AA.

What are going to do for chassis parts?

For heat shrink, I use all diff sizes and just picked up a variety pack from elsewhere.
