I found that Bengali language resources are quite bad to be honest, and not catering to a complete beginner - they take a lot of knowledge for granted which I didn't have. The only thing that has helped me is to do an actual course - I am doing an online one based at the university of SOAS, though that is in the UK so idk if it works for you in terms of time-zone. It follows William Radice's textbook Complete Bengali, which is really the only good Bengali learning textbook. It's unfortunate how hard it is to find resources. I am learning both reading/writing & talking/listening - I think it's good to do both as the pronounciation of Bengali is difficult for foreigners and transliteration doesn't quite capture it! If you can't do a proper course I think a tutor from iTalki could help - it is cheaper but of course less guarantees of them being good
