With the help of her brother, she had learned the basics of reading, such as sounding out words, looking at pictures for help, and using the dictionary.
Should there be a comma between "reading" and "such as"?
"With the help of her brother, she had learned the basics of reading such as, sounding out words, looking at pictures for help, and using the dictionary." I believe this is how it should be but I'm not 100%
It is correct the way you originally posted it. :)

Yes I feel the comma is coorect after reading because it would be too incomplete without it there. I added the semicolon because I feel it worked in the sentence and it's always good to show some diversity in your syntax!
I agree with your original sentence. It is grammatically correct
reading, such as: Don't be afraid of the colon marks. The independent clause before the colon should be able to stand alone. "... she had learned the basics of reading, such as:..."
