Very much so, Aman refers to the undying lands of Valinor in the uttermost west, where the Valar and Maiar and most of the elves now live. If this is just so much gobbledigook to you, then don't worry you are not alone.
You may notice in Lotr that many of the Elves talk about returning into the uttermost west. This is what they mean. It is kind of like the Vallhalla of Norse mythology in some ways (not the feasting and killing of course) but much like Bifrost, the Rainbow bridge to Vallhalla, Tolkien had the "Straight Road" that went off the edge of the world to Valinor. For more (and probably more coherent) information, try the Silmarillion, very hard going compared to LOtr and the Hobbit, but good for knowing this sort of thing.
Welcome to the Forum Gromdul, I hope you enjoy it.
