I think that Sam has a deep and profound love for Frodo, a true friendship, far from the shallow friendships that are most common in today's society. I seriously doubt that my friends would go to the lengths Sam did to keep Frodo safe for me. He followed his master's every whim, never criticized him (no backstabbing here), put Frodo's well-being far before his own, and put himself in danger to defend him. In Mordor Sam gave up his portion of food and water for his master although he was exhausted as well. As to the "closeness" of the two on the journey, such as sleeping close together, I think this was done for their survival. For one thing, they were cold, and this would preserve heat. Also, if they were trying to hide from enemies, sleeping spread all over the place would not be such a good idea. And I think that it's pretty obvious that Frodo's glowing skin is a result of the red lamp said to be hanging in the room.
