Just some background - I'm a big city girl and I will be travelling alone. I will be staying outside the park (I am leaning towards right outside the Roosevelt Arch) and I will have a rental car.
======================================

We went to Yellowstone 3 years ago, and traveled for 28 days in an RV in Aug/Sep
... First big piece of info..... I found Cell Phones do NOT work inside the park 90% the time...
... You will see PLENTY and all kinds of wildlife from the roadway and some are close...
... Second tip: Follow the Park Rules and DON'T get close to wildlife - Use Telephoto Lens
... Trust me... You will see many, many IDIOTs violate this rule --- NOT good
Regarding Roosevelt Arch....... Check: Rocky Mountain RV Park + Cabins
Below is URL for Website:
http://www.rockymountainrvpark.com/Very Nice Place, and a very 'small town feel' with friendly people... We stayed in an RV but, they have Cabins and I am sure you need to book way ahead..... You've been warned.. ha
Regarding Hayden and Lamar Valleys... Good Choices, and there is no such thing as a 'best' spot... the Yellowstone is a very 'Dynamic' environment and things change from day to day... Just 'Drive and Look' and you shall find...
With regards to finding wildlife and going early... YES, be in the park just before or at sunrise... and as you drive... just watch for other cars pulled off to the side of the road... BIG CLUEs.. ha ha ha..... and don't be afraid to ask others on the roadway... BUT, besure to be a "Good Interviewer" as you talk to people and get very good details... and write them down.... You will find that 5 min after you left the person you spoke with, the woods all start looking alike and the details start to 'fade' fast in your head... Get as much info as you can... I have found that other people just LOVE telling their 'Stories..'
With regards to bears... Since you will be alone, keep your eyes open at all times, and never, never try to 'directly encounter' bears or any wildlife... Consider the purchase of a LARGE bear repellent spray which can be bought at many of the Ranger Stations and they will give you good advice on the use of same...... We bought and carried two with use most of the times when out of the car.
With regards to astrophotography, any 'wide open space' is OK / Good for that, just keep in mind that 'Overnight' parking within the park is NOT allowed and strictly enforced. My suggestion is to ask the Ranger at a station, and be prepared with a good verbal response to a Ranger should you be approached and question as to what you're doing and your intent... I am former law enforcement (retired) and I spoke to a number of the Rangers there and they take the very seriously... OH, car engine and light off is Good for this BUT, stay near your car... Let me know if you would like some suggestions for 'phone apps' for this type of work.
BTW: One of the best 'Night Shots' I had every gotten is the 'Stars behind Ole Faithful' as it erupted... and YES, this can be done. Many, Many people do this from the designated boardwalk area at night... and some stay out there for hours trying to get the 'RIGHT'' shot.. ha ha.. Also, Consider taking a 'Somewhat' powerful flashlight with you for you will see other individuals who will use the same to 'Paint' Ole Faithful as it erupts during the nighttime... ha ha ha AND, you can park for free there in the Pk Lot, without having to pay during such events...
PS.......... Yes, Bears do go out in the rain
In closing........ hope you have fun and keep 'clicking'
Cheers
