Hi EdLeppur
My reply in https://www.pokerstrategy.com/forum/thread.php?postid=3114344#post3114344 covers some of your questions, except that I would recommend the No Limit Hold'em lessons overview instead
I would also recommend playing standard tables rather than zoom until you get quite good at quickly evaluating hands.
As for tools, I suggest that you get the free version of Equilab
Also, once you've settled in to Poker, I suggest you get a database tool like PokerTracker 4 or Hold'em Manager.
There are discounts for both tools if you get them through those links. Both have free trials, so try them both and pay only for the one you like the best.
Rather than buying a course, if you play on a site tracked by PokerStrategy.com then your status will increase, and as your status increases, then the entire PokerStrategy.com library of articles and videos will be available to you.
Also don't forget the coaching sessions on Twitch
You'll need a Twitch account. These sessions are open to all levels, and the videos are available on Twitch for a short time afterwards.
Later they may require higher status.
All the best,
VS
