Hello Jack,
There are a couple of threads regarding tissue culture on these forums. Have you read through them yet? Here are a couple:
Tissue Culture
tissue culture kits
Those threads above have discussions on sources and materials. The following link sells kits for home tissue culturing:
Kitchen Culture Kits - Intro Page
The best book for beginners that I know of is "Plants From Test Tubes" by Lydiane Kyte. Lowest price on the planet for this book is from Amazon.com
Have fun!
