This might be a stupid question but when just starting out do you need / or should you have an attorney look over your business offerings? price lists/ cake contracts? etc....

Price list, no. I can't imagine any lawyer knowing how to price products. But a cake contract, yes. And certainly a lease, if you're going to rent a storefront. 

I'll add trademark paperwork and operating agreement to that list

You may not need an operating agreement, but you certainly need to consider what business form you will use. An attorney can help you choose, and get you set up once you've made your choice. And as MimiFix pointed out, you should always have an attorney review any agreement you are signing, including your own contract.

At the very minimum have someone look over your contract. Things that are legal in one place might not be legal in another, and the language that they use can vary.
