Can't say anything about Dark Sun, as I haven't played that game.
Albion is one of my favorite of all games of all time though, so I can certainly recommend it.
It works well with DosBox 0.7, but there is also a windows/linux port, which allows higher resolutions, better graphics in the 3D sections and better performance.
You can get the windows version here:

Make sure to click the dwonload button on the bar at the top
Or the Linux version here:

edit: Here's a video of the port to give oyu an impression

Additionally, if you speak german, I recommend the german version, as that's the original language.
Apart from that, there no mods or utilities I'm aware of.
