Simon is indeed in the main series of the Mortal Instruments series, and considerable things happen to him during this time, due to his relation to Clarissa Fray, the protagonist of the story. You may want to skip the rest of this answer if you do not want any spoilers,
For one, Simon was turned into a vampire after being fed vampire blood by Raphael, the 'leader' of the Brooklyn vampire clan. However, he is special, since he has the resistance to sunlight, which has not been heard of.
Furthermore, near the end of the third book of the series, Simon was given the Mark of Cain by Clarissa Fray to protect him, but it cursed him by letting him live as a wanderer as long has he has the mark on him. However, he has it removed when he asks for the Archangel Michael's Sword for him to be able to break the 'bond' Jace has with Sebastian.
Finally, near the end of the fifth book o the Mortal Instruments, he has his immortality and all knowledge of Shadow hunters, including Clarissa, to be able to get everyone out of the demon realm of Edom.
Sebastian is the son of Valentine and Jocelyn and also the brother of Clary. Sebastian is also half Downworlder who is helping his father on his quest to take over the Nephilim and Shadowhunters along with the rest of the world.
a violin and a viola
Woodwind, brass, strings and percussion.
Relatively, it is one of the larger instruments, however, it is kinda in the middle size of keyboard percussion instruments. Smaller than a marimba and vibraphone, larger than a set of bells or crotales.
Same as all instruments, it rests on half, quarter, and whole rests
Both. At first he trys to kill clary and jace, then allies up with the clave and rest of the downworlders to beat valentine in the city of glass.

a violin and a viola
Definitely a snare drum, and piano. Unsure of the rest.
as long as sub-zero or scorpion is #1 the rest is up to you.
Woodwind, brass, strings and percussion.
No.
There are pictures of the rest centre in books, but there are no actuall paintings of it left. The pictures in the books are pictures of the paintings from 1946.
45 books. Third of 45 is 15. 15 of the books are mysteries. 30 leftover. half of 30 is 15 - 15 science books and the rest (15 books) are about cars. I better not have just done your maths homework!
No, Simon is infact the Christ like figure in Lord of the Flies. He has the ability to "see the future" and is more quiet and solemn compared to the other boys. The boys think Simon is crazy becuase he is not like the rest of them.
He feels guilty about murdering Simon; him and the rest of the boys kill Simon at the end of chapter 9
