Hi there and welcome.
I remember when I first considered building a guitar. I havent actually done it yet because I dont have the tools I need, but I do build full size models from MDF and Plywood. Good experience as I have pointed out below. I advise you to just learn as much as you can. there is always a learning curve with anything that is worthwhile. Ask questions and take on board what the more experienced people here have to say.
You mentioned Muhammed Suicmez from Necrophagist. I found a pic of him with a guitar...
looks like a Moser/BC Rich to me, but someone here may know more. Anyone? (Metal Matt should know ! :lol )
Melvyn Hiscox book is essential reading, as are the various posts on here that detail each step of a build. you can learn a lot from other peoples efforts.
Wood is ALWAYS the hard bit for new guys (and Gals!) as are the terminology used when describing stuff (3 part laminate neck thru strings thru compund radius 27" shread machine is the technical way to say "nice guitar!") Stick to what the experts use and dont try something too advanced for your first guitar. Maple, Mahogany and Ash are good places to start because most production guitars are made from these species of wood in my expeience. Exotic woods are really the realm of the self builder and the custom guitars they make.
Id say the place to start is to sketch the guitar out in full size. Then you will have measurements to plan what woods you need. Thats where the Melvyn Hiscox book will come in because it will explain about scale lengths, how the neck and body come together, Neck tilt, etc... I dont expect you to understand all those terms yet but it never hurts to start.
After you have a full size drawing, you should make a plywood or MDF template of your chosen instrument. It will give you a lot of experience on what to look for when it comes to build the real thing, AND you will have a full scale model to use as a template on the expensive woods.
Good luck. Remember to take photos of your progress, dont rush and most importantly, learn from your mistakes, but dont be discouraged if it goes wrong. EVERYONE makes mistakes!!!!
