you can download there 9210 sdk (newest ver is 1.2 if I remember right)
it has got all needed files + documentation + examples

have fun

PS.If you're new to C/C++ I encourage you to learn basics with PC as you can debug your programs much easier this way and once you know well what you're doing go for Symbian.
