Parts for XD75 / First Build

[PhoenixUNI]

Hey y'all! Looking at doing my first build here soon; settled on an XD75, as I've fallen in love w/ the split layout.

I've been surfing around KPRepublic all day, and think I settled on all the parts that I need. Just wondering if it's proper, and a few questions off of it.

First, the parts.

• PCB: XD75RE https://kprepublic.com/products/xd75re-xd75am-xd75-xiudi-60-custom-keyboard-pcb?variant=958306058284
• Case: https://kprepublic.com/products/stainless-steel-bent-plate-case-for-xd75re-60-custom-keyboard-enclosed-case?variant=996689870892
• Plate: https://kprepublic.com/products/stainless-steel-plate-for-xd75re-60-custom-keyboard-mechanical-keyboard-plate-support-xd75re?variant=1199000387628
• Switches: Gateron Blacks (3-pin) https://kprepublic.com/products/gateron-switch-3pin-5pin-smd-blue-red-black-brown-green-clear-yellow-silent-for-custom-mechnical-keyboard-xd64-xd60-eepw84-gh60?variant=9518676508716
• Cable: https://kprepublic.com/products/bold-coiled-cable-wire-mechanical-keyboard-gh60-usb-cable-mini-micro-type-c-usb-port-for-kit-diy-poker-2-xd64-xd75-xd96-mobile-phone?variant=9121130315820

For caps, I'm going to pick up the MDA Big Bang V2.0 https://kbdfans.com/collections/mix-profile/products/mda-big-bang-v2-0-keycaps-set

So my questions:

• Do I need to purchase LEDs to fit into this? If so, which ones?
• I've never soldered before; don't even own an iron. Is it worth paying KPRepublic the cost (I think it's around $20 total for switches and LEDs) to solder it all for me? Or should I attempt this?
• Anything else that I missed completely? First build, so wanting to make sure I've covered all of my bases.
