Can i design in software such as cambam,generate gcode,put code onto a memory stick then transfer to the machine computer with mach installed

Yep, that's what I do.
You could use network to transfer the files, but that's just something else that could potentially slow down / generally annoy Mach 3. The computer needn't be anything special. I'm currently using a single core 3Ghz P4 with 1Gb (might be 2) RAM which is plenty.
