N00b map maker needs help :D

I'm kinda a n00b at map-making.. Can anyone give me a small guide to how to get started (like I know how to create a surface to start on, but then to add the texture to it, add trees/guns, buildings/stairs, get some hills and stuff in it, etc...) I've tried reading guides, but seriously they don't explain the parts I wanna know...Also... if you can build stairs and the other things using the buttons on the side that comes with UnrealEd, how can you move them about so they fit together and things (cause once I try to make them, I make them then cannot move them anywhere
).. Sorry if I sound like a HUGE n00b... BTW... I have some good ideas for maps (or I hope
)... Any help would be GREATLY appreciated...
