Howdy again Noah,
If you scroll down to the bottom, just above the reply box, there should be a field to select a status option.
I am not aware of any free WordPress hosts that let you upload your own custom plugins and themes. You will need to purchase one. As far as I am aware they all come with support. You would have to consult with each host to find out what type of support they offer, and how much it covers. Most of them state their scope of support somewhere on their site, although you could contact them with specific questions.
