1: Myself, I use battlemat (
Here the map of my adventure). You need to upload you map (mine come from an adventure published in a pdf of Dungeon magazine), but you can probably find a lot of map on the web, or anything drawn by yourself.
You need to upload your token (All my token come from the web or the character generator). After that, only the master, and anyone allowed by the master can move, add or remove any token around. I love the simplicity of this website.
2: That is the trickiest thing about 3.5, one reason I preferred to run pre-made adventure. One thing why I find it a lot easier to DM as a 4th edition master.
