It's really not that hard to follow that map mate. As JD said, just come out at the Kop end and turn right. Follow the road downhill and you'll come to a give-way just past a school. Keep to your left there and follow the traffic downhill until you come to the second set of traffic lights. You want to turn left there - going the way the main road bends, plus you'll see some five a side football pitchs on the other side of the road.
And then that road heads straight down to Lime St - you should see some sign posts for the Mersey Tunnels. You should get a cab a bit further down that road if you can't be bothered walking it.
