I know exactly what I want it to look and sound like and want to simply assemble warmoth parts. Problem is I don't have any idea what the radius I want is...if I want it to be gibson/fender scale...tuning peg hole size, jack size, among other things.
That's totally understandable. It's how I ended up here myself!
I've got my mental picture of what I want to build, and also have some digital mock-ups to either confirm something was a good idea or prove that it was a terrible idea.

And during the design phase, I also Bob-Rossed myself and stumbled into some happy accidents that I wasn't expecting but took the design in a different direction.
Lots of Internet research all across YouTube, from builds to finishing to pick-up selection. Aaron's videos are incredibly helpful, especially the one posted about conversion necks and how a Gibson scale is meant for a certain type of body versus a baritone scale neck for another body style. I especially like Darrell Braun and Brad Angove on YouTube.
I look at guitar building the same way as guitar playing. When I first picked up an electric guitar, I had no idea what I was doing. Not a clue about electronics, amps, effects, none of it. I picked it up assuming that I could just plug it into my bedroom stereo system and be cranking out rock'n'roll. I thought the guitar was a POS because I didn't get what was in my head right away. It was another 2 years or so before I finally learned what "amps" are (I was a sheltered kid, and this was an era long before Internet).
Fast forward over 30 years later to modern day, and I'm
finally getting better at playing triplets! Still can't explain to you how to play specific augmented and diminished chords, though.
Point being: don't beat yourself up for not "getting it" right away, especially if you're staring at the big picture of the whole guitar all at once and getting overwhelmed. Narrow the focus and zero in on one component at a time. Learn the options and characteristics of that one component, write down which one(s) you prefer, then move to the next component. Then, since you're armed with knowledge about component 1, you can come back to it to readjust if something you select later down the chain won't be compatible with it.
