Good news, a few outlets have created street maps / information for each town. You've already found The Guardian's one.
The Telegraph has town-by-town maps and street descriptions - although it's not drawn directly on the map, you can follow the directions. The route was plotted using Locog's PDFs of the torch route, scraped into a database by ScraperWiki.
Fortunately there's always a geek out there who makes something like this. Google Maps Mania has a post which lists several. It includes Follow the Flame with Figures which is a Google Map and calendar of the Olympic torch's route around the UK, created by the UK's Office for National Statistics. The map shows the route that the torch relay will take and includes a calendar function to see where the torch will be on a particular date. The map includes a postcode search function to find out where and when the relay will pass a particular location.
Tripline has several pages worth of dedicated people who have built maps of the route. This includes overall maps as well as individual city maps.
