Well, that's easy, I think you might already know how to do this by now, so sorry if you do, but here it is in steps:
1: Download the map you want
2: It's a .zip file, right click the folder (best to download to desktop) and click extract here, or extract all, if it's extract all, choose to extract it to desktop in it's own folder
3: Rename the folder World# with at the # the world you want it to be when u select the world.
4: Restart minecraft and the world should be there
If you have any inconvenience still trying to play the custom maps, feel free to send me a message at: louistimmer@hotmail.com :) Hope this is what you were looking for.
It depends on the map.
on www.halomaps.org you can also get heaps of tags and homebrew maps there to!!!
There is a download in which you can get 64 player size maps. Here's the link. http://www.fileplanet.com/156004/download/Battlefield-2---Single-Player-64-Maps-Mod There are also websites, forums etc in which "hackers" have found ways in which you can get 64 player size maps. It is tricky though and it's probably a better idea if you download them but if you can't download you can try that.
Custom maps? You will have to setup a server, download the map and replace "world" folder with the custom map (Must be renamed to "world".) Or you can play on my server and we can set something up. I will setup world file and all that. Just tell me the map and your IGN! (In game name.) Email me at: dave_robertson@mail.com
This all depends on your maps. A copy of Minecraft that has no started maps is around 228KB. But after you start playing this will go up.

If your talking about the Curse.com minecraft forums, then go to the maps area of the forum, then there should be a button called "are you an author of a map?" or something similar. go click it and you will reach the upload page.
