I just installed TOTSC and I'm in Baldurs Gate where I was just accused of murder, I can't figure out why I can't find any new maps like Ulgoths beard and that stuff. Could anyone help me out?

You'll have to "activate" the maps - just go the area with the bridge just outside BG - and exit to the North.

That shouls bring up Ulgoth's Beard. And from there you will get access to all the other areas - just talk to strangers.

I went to the north of the bridge map and exited but there was just a guy on a farm who wanted me to kill soe zombies. Is there something I do from there.
