I'd still say don't rush. For example ...
I mainly build with a zero fret, so I don't need nut slotting files (OK, I have them, but most of the time saw slots in the spacer 'nut' are all I need). A zero fret might be a good choice for a first build, because getting nut slots right has a strong element of 'feel' to it, and there is enough else to learn in a first build. Design choices tell you what tools you need right now.
Same with a fret jig - I mark my frets with a knife along an engineers square and then cut them by hand, and this means I can choose any scale length I like. Lots of fret spacing calculators online.
If you're planning an acoustic guitar, maybe even consider making a ukulele first - much smaller, so less planing and sanding involved, and a tenor or concert size is quite forgiving of minor construction blunders and will still be playable, which is encouraging. Don't try a soprano uke - uke builders agree that those are hardest to get even playable! You could make one from 1/16 ply for back and sides (paint those) and a solid wood top, and the neck from an old wardrobe, so the materials would be cheap enough to burn if it's a disaster. My first build was ugly and chunky but it made a nice noise, and I learnt a huge amount from that first one (including that it began to break up after a couple of years because I'd made bad wood selections). No-one ever makes just one, unless they give up after the first doesn't go quite right.
