I have some files of these two types, but I can't find any way to play them. I can't even find any information about the lwav file type, but xma files are apparently a file type for Xbox 360 audio. Does anyone know how to play them, or convert them to an file type that can be played?

For either one, I'd recommend Foobar2000 (http://www.foobar2000.org/download) and These Components (http://www.foobar2000.org/components/tag/game+music). Once installed, you should be able to DnD the files in question and play them from there. If you right-click them in the player, you should have the option to convert them, as well [for mobile phones and other portable players].

That said, I can't guarantee that FooBar will play whatever files you have for it, but I think it's fairly likely.

Sidenote: There may be some other components that you might need as well in order to play your files as well. I'm not familiar with XBox360 audio enough to know.
