What are the really important Mitzvos in Judaism?

The Gemara in Makos (24a) states that there are 613 mitzvos but that the Prophets boiled them down to a much smaller number of important Mitzvos.

Michah gave three Mitzvos for people to focus on - "Asos Mishpat..."

1. "Asos Mishpat" is monetary laws;
2. "Ahavas Chesed" is bestowing Chesed;
3. "V'Hatzne'a Leches Im Elokecha" is escorting the dead and bringing a Kalah to Chupah;

Yeshayah later gave two primary Mitzvos - "Shimru Mishpat va'Asu Tzedakah." 

It is fascinating to see what the Prophets listed as their critical mitzvos and what they left out.

The Mitzvah of Talmud Torah is not mentioned in any of these lists. In fact, these lists are all interpersonal mitzvos, there are no mitzvos bein adam lamakom listed. 

It is unbelievable how far orthodox judaism has strayed from these principles.
