In general for improvement I wouldn't recommend playing more than 2 tables.
Your other questions are basically impossible to answer. I think RIO just made their essential plan free for a while, so something like that or the upswing lab might be worth looking into.
I suggest sharing more about what you're doing and getting feedback + doing some searching on your own, rather than asking extremely general questions.
Personally, I also would suggest depositing 100-150 and starting at 5nl instead of 2nl, but the approach of starting small and studying a lot is a good one.
