One super helpful tip I got from an actual trained draftsman is to use harder pencil lead for your layout and construction lines. Like 6H to 9H. You'll get a much lighter line to erase later. It'll also hold a finer point for longer.
I prefer lead holders to wooden pencils. They take 2mm lead, and you sharpen them with a lead pointer. K&E pointers are readily available on eBay, as are the abrasive cups that do the actual sharpening. The plastic trash can ones will get the job done, but are unsatisfying from a tactile standpoint.
A decent lead holder is a trick to find. The Alvin one I bought is too loose and the lead slips up into it. The Staedtler one doesn't close tightly at the tip and support the lead well enough to prevent breaking. The Prismacolor one is satisfactory, and I inherited a vintage one that I love from the aforementioned draftsman.
I recommend an erasing shield to make revising your pencil work without erasing too much. Another person I know with an art background tipped me off to putting tracing paper over your main drawing to iterate on details before committing them to paper to reduce erasing.
Drafting vellum is pretty forgiving of erasing, but it has a toothier surface that can get a little dingy if you're working on a drawing for a while. I've never tried Bristol board; I don't need immaculate drawings for reproduction, just good enough ones to build from.
Happy drawing. It's an immensely satisfying process for me. If you're detail oriented, you'll likely find it enjoyable too.
