It sounds as if your tool knowledge base is essentially zero. With that being said, you might try your local library and see what they have available on tools and tool collecting...it may not be much.
Look at the Astragal Press web site. They sell many books on tools and tool collecting. They have several books on tool identification. The one by Alvin Sellens is quite good, as are the ones by Salaman.
Think about joining one of the tool clubs. The Midwest Tool Collecters, Crafts of New Jersey, The Early American Industries Association, and the Missouri Valley Wrench Club, are just some of the many groups that do an excellent job. All of the above have quarterly publications with excellent articles and information.
As for the value of your stuff, the quick answer is no they aren't worth much. But without knowing who made them it's hard to tell. Condition is extremely important, old rusty tools like yours tend to not be valued very highly.
Look at the Alloy Artifacts web site for help on wrench identification, Randy Roeders Old Tool Heaven site for Millers Falls. Try Jim Bode's tool site for an idea of the value of some old tools.
Good Luck!
