Alright, thanks a lot guys. Loads of useful information here. Sorry about not posting the pictures, had a pretty stressful weekend. And Guild Wars...
In terms of design, I guess I'll get rid of the outer channels. I also have no idea of how to ramp, so I'll just cut a little bit at a time and keep at about 20 IPM. Usually, I plunge at 1 IPM for a small tool, sometimes even less. Since I'm using the 3/32" endmill, I have to be extra careful. I always cut under coolant, so heat and small chips shouldn't be a problem.
