help planning for my Las Vegas Wedding

Do you have a specific wedding and reception venue booked? If so, it would make sense to get the save-the-dates out soon just to allow people to plan out vacation days from work. (The distance may not be an issue for most people.) As to hotel rooms, it just depends on preferences and if you have lived together, there is not a reason to have different hotel rooms, unless you are wanting to get ready separately from him.

Maybe some others will chime in as you provide a few more details.

I would focus on booking the venue first, if you haven't already done that. Then give the VIP's a heads up about the plan, because people will need to play for time off budgeting etc.

I'm not sure why you would book two rooms for yourselves. I would just stay with your spouse in one room.

Congratulations on 10 years! I would check the courthouse on their hours as your event is on a Monday, but generally all you need is 24 hours for a license. I'd make informal phonecalls as save the dates or send out paper versions ASAP. They don't need to list venue location, just city and date for now. As for venues, most resorts provide options. You can easily view brochures online and get quotes by emailing their wedding planners. I don't think your guests need to stay in the same hotel as they are most often within 5-10 minute cab ride from each other. There are also independent chapels on the Strip. Las Vegas is a romantic town and very wedding friendly! Best wishes.

Oh staying separate or together is your personal preference. You can always get a 2-bedroom suite with a sitting area if you want some surprise.

One little thing you can do ahead of the trip is to start the wedding license online. Mostly this will just get the paperwork process started so you don't have to fill-out stuff while there.
