Per previous responses, some of this might depend on what temperature you're diving. Ultimately not much is going to change with temp, however, with a single tank, having some ditchable weight would be good. Instead of bolting weights to plate, you might consider weight harness such as the DUI harness as you could be lugging around a fair amount of weight, especially if going with a drysuit.
If you want cheap, you can't do better than just getting a harness kit and a stainless plate/wing. You can add any type of d-rings on shoulder/hip/crotch straps as you see fit. Once this is set up, it will last a very long time.
X-Deep bolt-snaps: with dry gloves or thick wet gloves, they are worth their weight in gold. These are great for pony/deco bottles, but useful for lights, or other items.
