As posted that information has about everything you need to know. I would add that drawing a tag is pretty tough. You pay $10.xx for an application each year, each year you don't draw you get points that increase your odds for future drawings. If you are drawn, you pay an additional fee for the actual license.
You don't have to have a guide but you probably want to at least have some people to help transporting the animal if you are successful. Given that the odds are low, it's sort of a once in a lifetime opportunity so you may want to hire a guide to assist you to increase you odds of success. The guide is what is going to cost you a good bit of money, and they may be able to get you access to private lands. Guide services differ and many also include lodging/meals.
However, there is a fair amount of public lands in the elk range also. If you're going to do it yourself I would be prepared to do a good bit of research and scouting.
Elk hunting is certainly a bit different than deer hunting in some ways and elk are more of a herd animal especially during the rut. Scouting and getting familiar with the area is going to be key.
