Verbes les plus utilisés en français – what to learn/how to learn? Dear italki users, French learners and teachers :)

I want to expand my French vocabulary (being a total beginner) and thought that an awesome idea would be to start with the most commonly used verbs.
I don't know that much of the French grammar yet and I don't want to focus on it too much, but it would, for sure, be useful to know how to conjugate those verbs.

The only thing is that looking at the conjugation tables makes me feel a little bit overwhelmed. So my question is: What do you think, what verb forms/tenses are most commonly used and would be more useful in the early stage of learning?

Please don't get me wrong, I don't want to take a shortcut. I'll learn all of those forms one day, but now I want to filter the pieces of information I can find on the Internet and start speaking as soon as possible. :)
Btw. Do you have your favourite method to memorise the conjugation forms/ learn how to use them properly? :)

Best regards,
Paulina
