Luggage and bags:
Travel in Germany is tricky. With the changing weather be prepaired. Pack extra clothes to add layers of clothes with changing weather depending on the time of year you travel in Germany. When I was there it was one of the warmest May's they have had. But in June it was also one of the coolest June's they had. So you have to just use common sense.
Clothing/Shoes/Weather Gear: Well, good walking shoes are a must, walking is the best way to see all of the sites in Germany. I wear black pants with a nice shirt. And a light jacket for the cooler days. I travel in early spring so no need for heavy coats. And take sun screen for those sunny days that can happen in the Rhine Valley.
Toiletries and Medical Supplies: No I never worry about such items. You can get any medical or toiletry item if you run out in Germany. Stores are well stocked with any item you need. That you can pack light and worry about other more important things.
Photo Equipment: The camera is a must. Batteries, never a problem. To charge my camera I have a charger that fits all of the different wall sockets around the world. I am prepaired for any country I travel to.
Miscellaneous: Spend some time an see the local sites. You can find information on the web at WWW.Mannheim.de It is in German but thats part of the fun. Use your dictonary and practice learning some new words.
