Long before the internet I built my first rifle when I was 13. I didn't know I was supposed to spend two years studying how to books, didn't even know they existed or where to find them. I had a barreled action with a busted and un-repairable stock, couldn't afford to pay someone to make me one, and replacement stocks weren't available. So I made a new stock out of a hard maple blank I bought at the hardware store.
My dad a couple of chisels, a few rasps and files and I bought assorted other tools as I needed them. That first attempt wasn't a real beauty but the gun shot great and I killed a lot of game with it. I also found I really liked the work so I just kept doing it, and more complicated builds as time when on.
All the reading and studying in the world won't make you a good builder, only building stuff will. If you can find someone for a mentor that will greatly speed the learning process but if not, jump in and give her a try.
I would save the expensive parts and kit for a later build and start with something a little simpler. My suggestion for a good starting place would be to buy a Lyman Kit or buy a cheap used Lyman for $300 or so, then buy a pre-carved stock, patch box and butt plate in the style you want and fit that to the barrel and lock. Then complete the shaping and finishing of the stock. This will give you a pretty good idea whether you like the work or not and you can move on to the metal work as you get better.
Best of luck and let us know how you make out.
