Correct, on the Pi2 leave it at the "stock" setting which can be trusted/guaranteed to work reliably.

gpu_freq is a shorthand for specifying core_freq, v3d_freq, h264_freq and isp_freq.
So:
Code:core_freq=500
gpu_freq=333
means
Code:core_freq=500
v3d_freq=333
h264_freq=333
isp_freq=333
(an explicit setting like core_freq takes precedence over gpu_freq)

There is no gpu_freq. There are 4 clocks on the gpu (core, v3d, h264 and isp) and gpu_freq sets all of them.
If you just specify core_freq=400 then the other 3 clocks will be default (250MHz).
