Decision is made-Divorcing my husband, but he is deployed. Any advice or things to know to start the process?

We got married young(he was 18, I was 21) and have been married 3 1/2 years. We are still young(21&24) and I don't feel as if either of us are happy anymore and don't really think anything is going to help us because we are both very stubborn and he lacks patience for anything really. I just really feel there are no common interests or sexual attraction to one another and there are definite respect and trust issues. So the decision has been made, on my part, to go through with divorce, but he is deployed until fall. I want everything to go as smoothly as possible for both of us, so that we can move on and begin being happy again. I'm not going to re-sign the lease in September and I want to get things taken care of such as moving stuff into storage and such, so that he won't have to when he returns. I mean, there's no point in paying $1200+ in rent for a place that I won't be in when deployment is over and he probably won't want to live in a big 3 bdrm townhouse alone. He can easily find another place to room with other soldiers or live in the singles barracks. The only question I have about the process is whether or not he is going to fight for any of the property we shared, such as our SUV. After we got married, I traded in my car from before we married, but I provided the credit to do the trade, but he had the income to cover the trade. I also used my credit to get the washer/dryer, bedroom set, and his new Mitsubishi Eclipse. But yet again he provided the income (I've had trouble finding employment). All I want is the SUV, the couch/futon, and some of our kitchen items and that's it. For all I care he can either keep those other items or we can sell them and split the money or something. I don't want to have to fight over anything, but I feel I have rights to the SUV. I mean I will need transportation to get me a job so I can support myself and he already has the Eclipse. So we will both get to keep a means of transportation. Is there anything I should know that will help keep this as smooth as possible? What are my rights as far as property items, and other things go?
