1. I love the Three Dog Night song that was playing during the VW ride, but I couldn't remember the name. So, I researched it on the Internet, and it's called Shambala. I then read the lyrics, and it was a perfect song for Hurley and his struggles.
Then, I realized I had no idea what or where Shambala is. So I did a little more research, and according to www.shambhala.com (and pay special attention to the capitalized word)...
Internally, Shambhala is the DHARMA chakra, located in the heart of all beings. It is the symbol for mind, completing the trinity of body, speech, and mind. Holy crap!!! This website mentioned Dharma!!!! Plus, with the lyrics and how this relates to Hurley, is this a coincidence? I don't think so. These writers are GENIUS!!!!!!!
2. The rabbit’s foot was one of two apparent references to the titles of earlier episodes. Episode 1.5 was “White Rabbit.” Episode 1.3, “Tabula Rasa,” was alluded to when Kate told Sawyer that they could start over with a “blank slate.”
The dart that Sawyer stepped on was most likely from the dartboard from down in the hatch. Of course, Sawyer and Kate don’t know yet that the hatch is no more, so they have no idea what a random singed dart is doing in the middle of the jungle.
Note that Niki is wearing a red shirt in this episode, suggesting she’s not long for this world. Another random unknown brunette was also wearing a redshirt during the reunion sequence.
Randy Nations, Hurley’s former manager and the manager-to-be of the ill-fated Mr. Cluck’s Chicken Shack, is the same Randy that was Locke’s manager in Locke’s first episode (1.4 “Walkabout”). Hurley purchased the packaging company where Locke worked, and most likely had Randy put in a management position because he felt responsible for him. Also, Hurley mentioned Mr. Clucks getting hit by a meteorite in an earlier episode, so that wasn’t knew. It was still funny, though.
Inside the bus, there was a lot of trash and the blueprints for a dirt switchback road. That will likely become important in a future episode.

3. It wasn't an Apollo Bar young Hurley was eating, it was a Polar Bar. An obvious reference to the bears...
