s far as the tent idea, consider a Hubba tent

Plenty of room for one person, go with the two person if you want real luxury. The key is you can sit up fully inside, in case of a rainy day.

Hennessey hammocks are great, I have two myself. It can work as a chair during the day, and keeps you up off the ground. Not your stuff though, thats an important thing to consider.
Make sure you take it for a test overnight if you haven't already. Hammock camping is not for everyone. Most users I've met replace the stock canopy with a larger one to create a safer dry zone for gear.
