I need some help with choosing a bible and study material.....?

So I need a new bible, different than my NWT but I'm not sure what to pick. My reading level is fairly good but I want a bible with notes that explain what the bible teaches/ is talking about. It also does need to be simple worded, as I can read but have a hard time understanding. I also need some books or pamphelts or something that explains eveything there is to know about christianity - including the trinity. And maybe some comparison books on true christanity vs. Cults/sects. So what books? Where can I find them? Please give me your suggestions! PS is a NLT study bible a good bible?
