Here is a really good article on how to prepare chemestry lab gear from an article in the February issue of Modern Mechanix.
The article may be old, but the procedures and tools are still very useful today. I found the methods of cutting glass tubing to be rather interesting, if not quite kid friendly ;)
You might find this book from Oriely intersting: Illustrated Guide to Home Chemestry.
Recently, getting your hands on a good chemestry set has been very difficult. The Chem C3000 set is a pretty good start.
