Used Book in Good Condition
Actually, you should put the seeds in water for few days to ferment them. This removes a coating that inhibits germination, supposedly. Then continue as above.
Pole beans you should just be able to save. Make sure you're not planting hybrids of either plant, or your saved seed will give you unpredictable results.
This book is often recommended. I read it and it was helpful, and will be a really good reference for when I can actually start doing it. There are other factors to consider, such as cross pollination and such, and they're all covered here for each and every plant you could possibly want to grow.
Also... I read Breed Your Own Vegetable Varieties and was fascinated. She touches on seed saving, and of course gets into cross pollination (on purpose this time!) and genetics and such. It was really exciting to read, in a total geek sort of way.

The strains are different due to different genetics which in turn means different ratios of cannabinoids and different high/effect. It's like all the various types of tomatoes out there, different sizes/tastes but still tomatoes.
Basically the plants have been 'modified' by people through selective breeding. Certain genetics/plants are native to certain areas, people started coming in, taking those plants and crossing them with plants from other areas to create hybrids. This process has been ongoing for a long time and thus we have thousands of hybrids of marijuana which means thousands of different combinations of the cannabinoids.
Selective breeding is not at all unique with just marijuana as well, can be done with all kinds of plants to make your own seeds:
