Hmmm.....
As a noob myself I had exactly the same situation.
What I did was to make a comprehensive list in a spreadsheet (to allow easy edits!) of EVERY single component I would need....and I do mean EVERYTHING! I broke it down into headings like BODY, NECK, ELECTRICS etc. For instance, it lists not only the screws needed, but how many, which size and type, and which colour. Some items were just a Y/N, like eg. Headstock binding Y/N? If Yes, size/colour/#plies etc etc. If you just sit down (ideally with some actual guitars to hand) and pour over every tiny detail, making a list as you go, I found it really clarified what I would need to get/think about/etc.
Not only did it serve as a buying guide, but it also helped to organise my mind!
It also helped me to decide on colours for the hardware, and to make sure it would all match up. I mean, no point having chrome tuners and a gold bridge really eh??
I have yet to find anything like this on the 'net. I've never seen a useful list/tool where you just pick the options appropriate to your desired build. Maybe I should do something with this.....hmmm!
If do decide to go down this route, be advised that the list starts to get pretty long!!
I haven't even mentioned tools, sundries etc!
Hope this helps!
