I use Eclipse and CDT. Really comfortable although Eclipse has a bit of a steep learning curve. As for hardware, you'll have to be more specific about you want to do with it. edit: now that I come to think of it, have a look at http://code.google.com/p/micropendous/ http://code.google.com/p/micropendous/. I don't know why not more people use USB for microcontroller programming. It's a really easy system to work with and you support more hardware over USB than through Arduino shields and at a fraction of the cost. Bluetooth, Ethernet (CDC), keyboards/mice, and Audio devices can all be picked up from places like dealextreme for mere dollars (including shipping:), and the protocols are all well-documented standards.
