Actually Storm C V3 is very good, and it comes with the Amiga DEV CD V2.1 :-)
Install that, and you will probably me amazed! It's what I use on my Amiga all the time. (I have it running now)
The Amiga DEV CD is probably the ultimate reference, however I would recommend(and it's not easy to do) that you find some books for Amiga programming, especialy the ARKRMs!
Oh, and somebody here has a beginners Amiga programming website that I highly reccomend. Check the links section.
