If you're looking for landscapes, Grand Prismatic is good, but not during the golden hour. The sun has to get up a ways in order for the bacteria mats to light up and contrast with the blue water. Bring a polarizer if you have one.
You can get some moody/foggy shots in Hayden Valley if the weather is right. It seems that in the spring it's usually quite foggy in there. Swan Lake Flats is a favorite of a photographer friend of mine early in the morning and he has the pics to prove it, but it is a looooooooooong drive from the east entrance.
Some of the geyser basins on the west side can put off a huge amount of steam in the morning, especially as the fog lifts, and I've seen some great shots taken from near the road as you look out over the basins early in the morning. Artist Point, at the falls, is a good location, but only after 9:00 or so in the morning. If you're lucky, you'll time it right and get a nice rainbow in the mist.
Some locations on Dunraven can be nice but those are more evening spots if you get a good sunset. You'll have to drive the road to find your spot since there isn't necessarily one particular pullout that beats the rest.
Thanks for the tips on the Grand Prismatic. It's definitely one of the spots, I want to visit.
Since we'll be spending an entire day at the park, I'll be looking to get some sunset pics in as well. I'll have to check out Dunraven. Thanks!

Grand Canyon of the Yellowstone with early light.
OK, that GC is going to be on the short list for consideration. Thanks!

Id think twice about this time of year to hike up the hill to the grand prismatic. Its still really cold in yellowstone. There will be a ton of steam coming off gp.
I was there 2 weeks ago and there was so much steam coming off gp when we walked past on the boardwalks you could hardly see. Not sure how it would even be possible to see it from the hill with that much steam coming off.
the grand canyon of yellowstone was really cool. We were kinda bummed when a few of the trails that led to the bottom of the falls were closed due to the trail being destroyed by water/mud. Those probably wont be open for at least another month.
Head to mammoth, that place is awesome. When you drive through the small mammoth town there are elk chilling everywhere. They're not as exciting as buffalo but they're still cool. You'll also get to the point where you will stop taking pics of buffalos since there are so many everywhere.
Have fun in yellowstone, its an amazing place.
I'm hoping that when we are there, at the end of June it will be warm enough to get some good views of GP.
Another vote for the Grand Canyon of YS... seems to be a popular choice. 
I hope to get up to Mammoth as well. Hopefully we'll have time to get there.
Thanks for the suggestions! Keep 'em coming!
