When I started playing, almost 30 years ago, the only way to gain harmonica knowledge was to buy records, and attend local blues gigs, hoping to see good players. I was fortunate to meet some great players early on, who mentored me, and showed me how to explore the harmonica world. Also, Chess reissued many of their classic 1950's blues recordings at that time. I was able to buy these at greatly reduced prices in bagain bins. My Little Walter, Sonny Boy Williamson II and Howling Wolf double albums are now cherished (and much used) treasures.
The Internet opens the world of harmonica to all of us (this course being an example!). Becoming harmonica literate is now far easier. Below are links to harmonica players and harmonica resource sites. Work through these slowly, and absorb the wisdom they contain.

Brendan Power is probably the best known player of Irish harmonica, due to his album "New Irish Harmonica" and his work with the Riverdance show. However, he plays a wide variety of styles, as his web site indicates. He uses altered tunings extensively, which enable stunning ornamentation for his Irish playing on chromatic harmonicas. His approach to Irish styles is outlined in his book "Irish Music on the Blues Harp," and is highly recommended

I have used this software extensively for practice, and cannot recommend it highly enough
