If you want to make new maps for Halo Custom Edition you will have to start by downloading the HEK (Halo Editing Kit) from any number of places. If you just want to play custom maps, without anywhere near the same amount of hassle as creating your own I might add, then you just need to download the maps that you like the look of and install them.
You don't actually download any of the content when you download Halo CE... you just get the basic stuff.
