Welcome Snowshu, yes there is much to learn, but don't feel like you have to learn everything all at once. Learning photography is like building a house. You first begin with a good foundation, which is an understanding of exposure basics and build on it from there. There are many good books on photography, both film and digital, and a good one is as good an investment, if not more, than any single piece of equipment.
When I started in the early 70's there was no internet, only a few books you could find either in the library or a few magazines like Popular and Modern Photography. And cameras were all completely manual. I learned photography mostly through self education and A LOT of film, paper, darkroom chemicals and trial and error! You have so much more information at your disposal then we did 40 years ago!
