Why is the first phrase "Voy a leerlo" and not "Lo voy a leer"? Or why is the second phrase "Lo leí" and not "Leí lo". Could I say either for both phrases or is there a rule where I would have to say "leerlo" and "Lo leí"?

You can say “Lo voy a leer.” Both ways are correct.
You can’t move “lo” in “Lo leí,” though.
Direct and indirect object pronouns can’t attach to conjugated verbs unless they are in the gerund or affirmative imperative forms in which cases they must.
The gerund: “leyéndolo” (reading it)
Imperative “léelo” (read it - an order)
Apart from the exceptions, they must precede the conjugated verb or be attached to the non-conjugated verb (the infinitive) if there is one, like in the first example.
Is it obligatory that the pronoun be attached to gerund? For instance, “mi amigo me está llamando” sounds good as “mi amigo está llamándome”
Both of these sentences sound good. The pronoun does not have to be attached to the gerund as long as it is placed before the first conjugated verb in the sequence.
Ex)
La maestra está ayudándome.
La maestra me está ayudando.
They both sound perfectly fine.
Now that you mention it, you’re right.
It depends on the way the gerund is being used, though.
When it’s preceded by another verb, it can go either way.
When it’s on its own, the DO and IO must attach to the gerund.
For example:
“He visto a Rosa dándoselo a Marta.”
Ah yea you nailed it, I could not put that idea into words. Exactly
