A little late response but I thought I would share my newbie 2 cents after 2 years ago I went through what you are about to...
I would suggest you focus on riggers and planers with mono i.e. only the "basic stuff" and wait for everything else. You will not spend as much if you take it one step at a time, get handy with one type of stuff and then move to more advanced such as wire trolling or lead core or whatever... You may eventually hate some of the stuff that goes through your hands until you find something that you like and enjoy. Fishing rods/reels is something very personal to many anglers.
I am sure there are many good rods and reels, but my setup for lake Ontario is 6 rods Okuma Blue Diamond BD-C-1002MHa, they are absolutely outstanding rods. They are technically dipsy-diver rods, Medium Heavy, but I am using them for downrigger and planers. All 6 have Okuma Convector CV-30DLX reels spooled with 40lb Big Game mono green color, you can order a big bulk spool that would last you for quite a few seasons.
I had initially Okuma Convector and Magda, Daiwa Accudepth, Penn Warfare and Rival reels, I hated the Penns for flimsy handle and malfunctioning drag (to be fair, Warfare had a recall on bag drag but I did not know at a time so I returned them and bought Okuma Cold Water instead, which I am using for my dipsy set up with Daiwa Accudepth ACDDR1062H rods). Certainly, for more money you can buy more fancy and better reels, but budget-wise, Okuma Convector is THE REEL. Cold Water is even a better reel and now you can get them at size 30 from Latulippe ($127). Same for Daiwa Sealine, good reel.
IMPORTANT NOTE: You must loosen the drag at the end of each trip or it will stop working over time.
When I go to lake Ontario with 6 rods, I run either 2 downriggers and 4 planers (Church Tackle Walleye, no flag), or in deeper waters, 4x downrigger and 2 planers. The idea is that 6 rods/reels are the same, no need to focus on what rod goes where, especially when you are just about to start trolling.
Next, I have bought a stacker release from Scotty, cut it and made 2 single releases with 1 clip each using nylon coated steel wire (36-48 inch length). The mono on the release will start coiling as soon as you unpack the releases. I also attach an extra snap to each release with the same mono that I snap to the downrigger cable so that when you bring the ball back, you do not lose a release. I always set the tension on just behind the black line on Lake Ontario.
I typically use Luhr Jensen dodgers or flashers (8 inch) or 24-28 inch cowbells with Shoehorn spoons or Coyote spoons behind them, on 40-50 lb fluoro leader of 20-24 inch. Last 2 seasons were great with just these. This year will be adding flies, dipsy and spin doctors, flies bought on clearance but re-tied with 40-50lb fluoro, once all this BS with the lockdown is over. Still on braid. May be 1-2 years I will change to wire as it seems to be the preferred dipsy set up for many pros.
When you do to lake Erie, you can technically use all these rods/reels you are using for lake Ontario, just use worm rigs or smaller spoons. I would only add 2x rods of 8.6 feet, ML power such as Shimano TDR (TDR86ML2C) or the above Okuma Blue Diamond BD-C-862MLa for downriggers ONLY and either buy or make a dedicated light releases with a smaller clip. Alternatively, you can use the Scottys or others and just adjust the tension. Also I would use planers with flag because depending on the day, the walleye bite is barely noticeable (hence ML rods and light releases for the riggers).
That's my 2 cents. Any questions, shoot them down here or PM.
