Can anyone tell me where to get the gcc compiler from? is it on aminet? does it come with any good doco's?
Try
http://www.geekgadgets.org and get gcc 2.95.3 and related gg tools. The version on Aminet is even older and should be avoided. The docs are not very good but if you follow to the letter, you should at least get the thing installed. Get the OS3.9 NDK from Amiga Inc. Be prepared to download 20-25 MB total. This will need 50 MB or so on your HD.
Also, anyone out there thats usings stormC 4, can you tell me if its good/bad/ugly and if it is worth the discounted asking price?
Depends on your needs. To get started with C, the free gcc and the free Amiga NDK are all you need. With StormC, you get additional parts, such as a debugger, an editor, gui-driven make etc. If time is worth anything to you, 49 EUR is an excellent deal. You will save yourself the hassle of downloading and installing countless parts, and on top of that get software not available freely, such as the debugger.

Don't even think about using gcc with that setup, it would be very painful. gcc is hardly usable on machines 20 times faster than your hardware. For your system, I'd recommend SAS/C (via ebay). It comes with a debugger. If it has to be free, try DICE. Another free option is vbcc, which, unlike DICE, is still supported. But I have no idea how fast it is on a 030 with 8 MB RAM. If I may give you an advice, get rid of that horrible setup ASAP. A cheap used PC with WinUAE (100 EUR total) will make an enormous difference.
