No, you got it right; "ils" is used for any group which contains at least one masculine member. Some languages have a neuter gender, but not French.
Yes. This is the correct pronunciation.
If you play a string instrument you'll know there's a way to pronounce "bowing" that sounds like "low". What a mess.
I like this, but I think it would benefit from a translation, so people know what's being said:
"Hello everyone!
My name is Twilight Sparkle.
I am a unicorn.
I like to read magic books.
I have many books.
I live in a library.
Also, I am French.
French is easy with My Little Pony!"
Here's some more on French: word order.
The basic sentence structure takes the same order as English: Subject-verb-object.
"Je mange une pomme." "I eat (am eating) an apple."
However, adjectives generally come after the noun, as opposed to before in English.
"un lit doux" "a soft bed"
There are exceptions to this rule, such as for adjectives referring to size, hence "Mon Petit Poney" for "My Little Pony"
Notice that nouns always come with an article, and that the article changes depending on the gender of the noun. We have "le/la" for "the", with "les" for both genders in the plural:
"le soleil" "the sun"
"la lune" "the moon"
"les étoiles" "the stars"
We have "un/une" for "a", with "des" for plural:
"un jour" "a day"
"une nuit" "a night"
"des heures" "(some) hours"
