On my travels to East and Central Europe I always try to get myself the latest edition of the "In Your Pocket" guide. These guides are very up to date, provide useful maps and offer all sorts of information for independent travels. Most of the tips can also be found on their webpage.
I already got myself the Wroclaw guide on one of my previous trips to Poland when I was at the airport in Warsaw. So I am sorry that I don't know where you can buy the guide in Wroclaw. The price is only 5 Zloty (2004).
Don't forget to pick up a free map of Wroclaw at one of the Tourist Information Centres. The map includes a little street register, the location of selected sights and some useful addresses.
The main Tourist Information Centre of Wroclaw is located at the Market Square (Rynek 14). The opening hours (Monday to Sunday) are from 9 a.m. until 9 p.m. in high season and until 8 p.m. in low season.
Clothing/Shoes/Weather Gear: Because of its history Wroclaw has more than its fair share or cobbled streets and paths. At the present time there are a number of areas around the old town that are being reconstructed. I saw one women in high heels shoes who came to a abupt halt as she was crossing the road. She just managed to extract her shoe from the cobbled stones before the traffic started up again. Another problem is various road works, around the city centre that seem to have few workmen and are progressing at a snails pace. Various obstacles have to be negotiated to get around the roadworks.

Photo Equipment: Bring a tripod for night photos, you can't always find a convenient substitute and they are better than rainy day shots. I obviously did not but this is still the best photo I got of the Old Town Hall.
