G'day Isaac,
They're a friendly bunch here, and they know what they jaw about, so just ask questions and you'll be sure to get helpful answers. So many helpful answers you'll be spoiled for choice to decide which way is the way to go.
I suggest you get some bits of wood to use for practice before you cut into the 'real' timber and ruin it. Get your muscle ,memory for how to use a scalpel to shave off just a few thousandths of an inch, or practice cutting to finer tolerances against a line.
First off, grab a sharp pencil and practice marking out on some of that practice timber and cutting exactly to a line..
Mostly, enjoy. and get a good supply of tinnies in, you'll deserve at least one after every session.
