Unfortunately 1.4 doesn’t have that coords plugin. You need to make a brush under your entire map, and make sure its Square. If map coords aren’t square you’ll get errorred. Hover mouse in x/y view on corners of squared brush, and look in lower right corner of radiant hud for your coords.
For the basic entities, there’s debate on what minimum entities are needed for different patches. Download EB’s Prefab Spawns and import it to your spawnless map. It includes wobj’s, info_player_~s, etc.

He has great learning .maps for other entities too.
