Welcome!
I've been there before, we here probably all have. The way I started though was going to pawn shops and finding the cheapest beater guitars and fixing them up with very inexpensive parts. I used to pay 40 bucks for a guitar body and neck that weren't exactly pretty, but, I'd clean them up swap them out with cheap pickups (at the time EMG Selects were my choice) set them up as best as I could, brush finished them, then found people who wanted a starter guitar cheaper than a squire strat. Nowadays though Craigslist is a great place to go.
I did buy the Guitar Player Repair Guide but I've always been terrible at retaining anything I read (I'm also a bad test taker, or as Daniel Tosh says "You mean you're stupid..."), but, I learn really fast when I get hands-on. During that beater guitar time I think I fixed up 8 guitars, and after about the 4th one i learned what intonation was, neck relief, string pull, truss rods...etc. I also broke a few guitars due to my eagerness and "Hmm I tightened this nut at the headstock as tight as it goes...who the hell put this metal rod in the middle of this now broken fingerboard."
Probably the best advice I could give is do the exact opposite of what I did and research and learn and practice before you build. Buy a beater guitar, tweak it, carve it, break it, set it up, break the headstock off then glue it back on. And take your freakin time, I'm an impatient bastich so my first Warmoth guitar could be a lot prettier but daddy wanted to play it now. As far as a workbench, a large desk or kitchen counter (if the wife, mother or mistress is ok with it) can server as a perfect workbench.
I highly recommend watching this Strat, build if you haven't already:

This guy is extremely (overly as well, but it's a good thing) detailed about the build, I learned about the science (and unknowingly the math part) of guitar building due to this build.
These are other good channels to go through:
Sully's Guitars - Dallas based luthier, funny guy too. I should take one of his classes one of these days.

Dave's World of Fun Stuff - Cranky old fart, funny as heck to watch, not recommended to have children around.

StewMac - Great vids, pricey tools, but he is a knowledgeable ol cat so these videos help a lot.

O'Brien Guitars - Mostly acoustic guitars, but he shows some nice cheap ways to grain fill and such.

Will's Easy Guitar - I like this guy, and not just because of the certain people who does intro for his videos...

As far as tools though, you'll definitely need screwdrivers and I recommend these:

I'm sure someone will say just get a cheaper set at a hardware store, but I like to have a set of tools dedicated to my guitars.
Guitar nut drivers, or you can get a set of sockets with longer shafts. Again, I like having tools specifically for guitars and it makes my workbench look cool:

Allen wrenches for your neck/bridge. Get the right size, make sure the bolts/screws are either metric or imperial. Again a trip to the hardware store for these will work just fine.
The Strat build guy uses a screw lube you can buy, but you can use candle wax. Some have said to use soap, but I've seen people get stabbed for bringing that up.
Ok I think I'm done rambling. You came to the right spot to learn about putting a guitar together, this place in the last year or two has taught me A LOT.
Good luck!
