Do not go with website tonight! Very very hard to use, you are limited and IMO not worth the money. I also wouldn't buy a year worth of hosting or services from anyone. Try them for a month to see if you like it first, that goes for any hosting company.
First step would be to determine the type of site you need. Informational? Blog? eCommerce with a cart? These are going to determine the type of site you need and the hosting and software that will run it.
I'm assuming you don't have experience with this, thus you should go for something that will allow you to set up without learning code and is manageable through an easy storeadmin/admin panel. Sites like website tonight via godaddy put out "dirty" code and run slow, not to mention godaddy has one of the most confusing control/admin areas that I've ever used. (and I hosted with godaddy for 4 years and still have my domains with them)
