I've been using MTA Map Editor for mapping, it's pretty simple to use, you just enter the world and you're like in a spectator mode and you go where you want and you start adding objects, it's that simple 
If you want to add it to the server just go to the mta installation folder and find the map you've saved and open it using notepad, now there are some letters and what not, but go to http://www.convertffs.com/ and just convert them, now when you have that just add these lines in your gamemode.
