This mod was part of a large project that appears to have never been completed. From what I can gather, it would see regular units replaced by space ships from Star Wars.
There is no clear list of new units (you are guessing what has changed) and for the most part you will need to manually import each SLP as the installation process is broken on modern operating systems (the included modpack installer does not pick up anything to install).
Additional Comments:
Essentially, you are downloading a large collection of useless files from an incomplete project. If you really want Star Wars in Age of Empires just look at Galactic Battlegrounds. Actually, that may be the best place to pull across graphics if you need them.
