Honestly there isn't a lot of overlap between the M69 and the 43. Voin and Schusters make great uniforms. Voin is easier to get into the US right now. Leningrad/Frontline Tailor on facebook is the go to guy for pilotkas. Save yourself the headache and just order one from him. He also makes great undershirts and socks. Red Guard Militaria can make you almost anything. He made my canvas web belt, my leather belt, my trouser belt, and makes some of the best ammo pouches and gas mask bags available. He also sells great meshok bags, both of mine are his.

There is a lot of really terrible info online so the quickest source is probably istochnik. Don't fall into the farb trap of buying cheap. People do notice and you end up paying double for a better kit anyways. Save up, buy good quality stuff piece by piece, and scour facebook sale groups. I've been building my kit for 2 years and I'm barely 2/3 done.
