Should I.....?

I read a review on amazon for Insomnia and they mentioned that a character in insomnia speaks to a character that was in Bag of Bones. Sooooo shall i read Bag of bones first before insomnia?

Nope. Read them in order.

It's a VERY small reference. You don't need to read it before Insomnia (in fact, I did but I missed the reference at first, lol). But you may want to.
