You can run through and complete new londo ruins without using using transient curses.
tomb of giants also is not too bad if you know where to go. you can run past the first giant dog into the hole to the next section. if you find the bonfire there you can do everything else without aggro the dogs or giants.
You have to be fast. Run all the way into the first building, pause near the center for a ghost to clear the door to the spiral staircase below. Run, drop, right, through the fog wall, up to the top. KICK the LADDER. It is a shortcut from the top of the stairs where the two ghosts rise up. you can skip the first building using it. Next, run into the next building into the fireplace and climb. If you are lucky you can make it to the roof. If you would rather kill the ghosts in that building, then run in, turn left, down, left and out, up the stairs, into the last building with the seal. From there use a curse, move forward to aggro the ghosts and kill them with a bow. You can get most of them. There will still be the banshee and another ghost in the building but they are not too bad.
